i have app drawing sketch for a given image. The function of this app is to take a photo from the device, apply a graysale filter which emphasizes the outline of the image, and then get the sketch.
And finally it draws sketch automatically. The app currently works, but the lines are very rigid and unnatural when being drawn. The goal of this project is to create longer, smoother strokes during drawing the sketch.
if you are experienced in image processing and very familiar with Xcode, pls apply to this project.
i'll give you more details via PM.
