Abstract

The main goal of this bachelor's thesis is to design and create mobile app for iOS platform, which will allow the capture of high quality image of planar surface. Application can be used in lots of use cases where high quality of captured image is needed, like capturing photo of contract, wood pattern or book cover. Main building block of the application is to capture set of photos of planar surface, which is then used for calculation of the resulting high quality image. Calculation is performed using OpenCV library. Planar homography is used for image alignment, the quality of the resulting image is then achieved by combination of image averaging techniques, increase of resolution and reconstruction of details using Lanczos interpolation and image sharpening using Unsharp mask technique.
