2014-07-24 05:22:15 -0600 | asked a question | Extract elements of GUI-Screenshot for visual test - MSER Hello, for a visual regression test I need to compare screenshots of webpages (different release-versions). I started with pixel by pixel compare. Actually I split the screenshot in different parts (maybe 10x10 rectangles) and compare the histograms of correspondending parts. Now I try to find an approach to find regions of interest (with coordinates and/or bounding box) automatically (tried edge detection and so on) like this: Example of image segmentation I found different articles on the web dealing with blob-detection. One method for that is Maximally stable extremal regions (MSER) which is provided in OpenCV. Feature Detection and Description Now my questions:
Maybe someone has other improvements or tips for my problem. Best wishes |
