The line spacing setting in OwlOCR is a setting that allows you to manage how the OCR output is divided into paragraphs.

In this example I have captured a paragraph of text from Microsoft Word. The text is formatted to have double line spacing (line spacing 2.0) in Word. OwlOCR on the other hand has the default line spacing setting of 1.0. Due to the mismatch in settings, OwlOCR divides almost each line in the output to be a new paragraph resulting in a less than desirable output.

By changing the line spacing setting in OwlOCR to 2.0 and then running the OCR processing again on the same input, the paragraph breaks are corrected to match the input.

If you are getting too few or too many paragraph breaks in your output, it can be a good idea to try to change the linespacing setting to something slightly smaller or larger, even if does not exactly match what you have set in your input document.


Changing line spacing to correctly run OCR text recognition on double spaced documents on the Mac

While in general the OCR engines do a pretty good job these days, none of them are unfortunately perfect. There's always a case where some word or character gets continuously incorrectly detected and one has to go back to fix it.

OwlOCR introduced post-processing rules to help with such scenarios. In the current version, using the post-processing rules, you can define a simple find/replace relation. Simply put, enter an input criteria and what it should be replaced with in the results.

We try to keep things simple, but there are some occasions that can lead to confusion with this one. It helps to understand when the rules get applied.

OwlOCR flow for the text recognition is

User chooses an input file or grabs a screenshot.

User clicks the OCR page or OCR all pages buttons to start OCR.

OwlOCR runs text recognition on the images, noting the locations of objects that look like text and what most probably is written there. These are called observations.

OwlOCR applies the post process rules to each observation separately

. Typically the observations are rows of text as they appear in the input image.

OwlOCR corrects the output by adding line breaks or spaces between the findings as determined by the user's settings.

 the post process rules are applied to each observation separately and before the lines are combined. This means that if you have a post process rule to look for "steaming hot sauna" and in your input image that phrase is split into two lines, it won't be replaced by the post processing rule. This is because when the rule is applied the lines have not yet been combined and as such the full criteria can't be matched. Future versions of OwlOCR may support changing the sequence in which the results are transformed.

Using post processing to improve OCR text recognition results

Running text recognition on an image on the screen

This is a very common use case that one can run into daily. There's an image already displayed on your screen and you need to run text recognition on it. 

Running text recognition on an image on the clipboard

If you need to capture all text from an image and it's already on your clipboard or it's most convenient for you to copy it to the clipboard, you can easily input it to OwlOCR.

To use an image from the clipboard in OwlOCR, select 

 from the menubar. After you've input your image, start the text recognition from the toolbar for the currently selected page or for all pages. 

Running OCR text recognition on an image file on the Mac 

There are a couple easy ways to select your image files to OwlOCR.

Drag one or more image file(s) to the OwlOCR window.

 from the toolbar or menubar to browse and select the files.

The images should appear in your OwlOCR. Then simply start the text recognition from the toolbar for the currently selected page or for all pages.

How can I use OCR to capture text from the Mac screen?

Run post-processing steps automatically after each text recognition. In this version we are introducing this feature with simple find and replace steps, but expect to add more advanced use cases in the future. Please send your feedback to guide the direction of this feature if you find it useful.

Some industries have domain-specific lingo that can be tricky for the language correction. Use Custom Dictionary to improve language correction results by adding your words as a comma separated list.

You can now select the folder where instant PDF exports and automatic screenshots are saved.

These new options can be found behind the gear icon in the toolbar or Menubar > Settings. If you need any help getting started, please don't hesitate to get in touch! 

OwlOCR v4.4 released! 

 the jist by now. 2020. Cringe, shrug and shudder. 

2020 - the year of fabulous missed opportunities. 

Death. Disease. Unemployment. Missed games and events. No Disneyland. Weddings canceled. All bad? 

Chase your dreams because nobody else will 

When California, and other parts of the world, started shutting things down earlier in the year, and today again, everybody had to make a choice. Here is your extra time, what are you going to do with it? 

You can't do what you did before, and time is constant so you're going to spend it in some way anyway. By conscious choice or not.

The popular choice was to use it to buy toilet paper. I tried that. 

Having done that and watched a lot of stuff on Netflix, I chose to put some of that extra free time towards things I’ve always wanted to do. One of those is entrepreneurship or at least building some fun side projects.

Why you can't lose when you're building side projects

I love working on different side projects. Let me break down what's great about them:

1) If you're super successful, you're set for life and you've won. Congrats!

2) If not, you've anyway built something that's worth something and hey, that's a lot better than nothing!  

3) If not, you've built something worthless, but you have probably learned something very useful in the process.

4) If not, let's go have a beer together and thus you've earned a friend!

Since this was talk about side projects, you and your dependants will be fine on your primary income regardless of outcome, so any success will be a bonus, and any loss won't mean you lose your home.

How I found what to build and why you shouldn't do that 

Shame on me, but my side project's inspiration was the anti-thesis of what all the cool kids say about how to get started. 

I tend to watch some of the sessions every year from Apple's WWDC event. In 2019 their Vision framework caught my eye. It was a highly optimised way to run text recognition right on the users' device and seemed to have pretty good results. The idea lingered and over the course of the next half year I increasingly started noticing when and where it could be applied to the Mac (or PC) environment.

The common denominator for the problem was this: there’s 

text on the screen you want to copy, but it cannot be copied.

This happens more often than you realise. 

Maybe the text is on slides in a video or Zoom conference, part of an image, a scanned PDF or a song name in an app like Spotify and the app developer didn’t think that field would get copied.

Solution is easy, right? Just read it and type it like a 15th century scribe.

…but that takes time, I’m a millennial, and the butterfly keyboard on my MacBook Pro is flimsy. Besides, I had learned about that nice first-party API so there was not turning back.

The other technology inspiration was SwiftUI, another cool new framework Apple released the year before that I was dying to try out.

I guess you could say that my idea was born from a personal need and reading up on tech, but if you have a choice, a personal or even better a broader need is the more important thing to consider. 

That is to say, the priority should be 1) what 

Hatching the idea into a shiny beautiful MVP

I had everything I needed. Idea, tech, cool stuff to learn and some time to build it.

I started working on a text recognition app for the Mac with the idea that this is something I'll personally use. I'll be sure to learn a bunch of cool and useful things along the way and that will be a success in itself if nobody else cares.

It only took a couple months to put together the first version of the app. 

The core functionality was that you could simply select an area on your screen and any text in that area is machine read and copied to your clipboard. From there on, you could paste to your notes or emails or whatever is appropriate in your workflow. All of this happens pretty much instantaneously, on-device, so it’s fast enough even for short text snippets and completely private for any business purpose! 

I was actually really happy how well it worked and tried to put extra emphasis to ensure any of my first users would also get a similarly great experience. The way to ensure that is through two key focus points:

. UI should be aesthetically pleasing, but more importantly UX has to be functional and intuitive. I focused on building something that is easy to pick up for anyone, trying to follow good design principles and limiting features in the first version. 

. It's better to have less features that work really well than a lot with bugs. This enables a positive feedback loop where users email you feature requests rather than angry bug reports. That keeps you motivated, your users engaged to your service and gives you healthy backlog where to add stuff.

How it's gone so far and has it been worth it 

Of all the metrics related to apps I value customer satisfaction most. 

The average rating for OwlOCR on the Mac App Store in it's first year so far stands proudly at 

 - roughly doubling in November which was super exciting!

I take monthly active users as some measure of stickiness of the app. I mean, it could be downloaded a gazillion times, but if people don't use it, what's the point? 

But there's a more important thing here beyond the numbers. 

Most rewarding thing overall have been the users that have reached out to express their appreciation of the work. 

In these pandemic times with on and off remote apathy, that has been a great source of inspiration and for those taps on the back I’m truly grateful to my fellow internet strangers.

Has it been worth it? Yes! When there's imposing commands and limitations on your freedom, a fun side project can give you some sense of control. 

You can still work in pursuit of happiness,

 despite the limitations. Side projects can connect you with interesting people, pave way for entrepreneurship or side income and help with isolation depression.

For me and OwlOCR, this year had exciting starting numbers, awesome users and a healthy growth rate, so I'm eagerly looking forward to the next lockdown and 2021 to see if this story can grow bigger!

(And of course hoping for an end to COVID-19. Thank you frontline health workers, you are the real heroes.)

How I turned lockdown into a side project and why you should too
