iPhoAT – feature extraction at subpixel accuracy
All tests have proven that iPhoAT is better in accuracy than most of available software / library (e.g. emgu) Subpixel accuracy is amazing
Photogrammetry
Cross Correlation Exercise
Based on prof Cyrill Stachniss lecture I have decided to test the quality of cross correlation with subpixel accuracy. Results can be found below. 4 overlapped images have been tested from 2 different strips. High level matching achieved only when 2 images belong to the same strips, in other case Read more…
