I’ve mentioned some resources about image processing on the iOS platform with OpenCV and here’s a user interface control submitted by Maximilian Mackh that puts this into action.
This control provides a UIImagePickerController replacement with a custom toolbar and image cropping tool created for the scanning of images.
The documents image is flattened out (there is automatic document edge detection, and you can easily adjust the document selection with the built in cropping tool). Documents are automatically flattened out using a morphing algorithm and OpenCV so even if the picture wasn’t that great you can still make it readable. There are several other options for tweaking for the right size.
Here’s a set of images from the product demonstrating the control at work on an image:
You can find MAImagePickerController on Github here.
You can see the control in action in the instaPDF document sharing app.
A great project to look at especially if you’re looking for something utilizing OpenCV on the iOS platform.
