EigenFaces

CV Project 3: Eigenfaces Used std::vector instead of std::list in the implementation of findFaces. I tried importing to use C++ STL sort function but the program didnt accept the linkage. Hence, I had to write my own quick sort algorithm for this purpose. What worked? The interesting & the neutral as well as group folders worked really well. What didnt work? My program experienced really bad genralization errors. I tried number of test files of various scales with different min/max thresholds but the results were pretty disappointing. However, since the insample result...

Panorama

CV Project 2: Panorama Mosiac Stitching 1. For "make your own 360 panorama" took 17 translated imgs of WashU's Brookings building with Iphone SE using hand (no tripod). I converted the imgs to low (640x480) pixel using imageMagick's convert tool. 2. Initially found (in mm) = 4.2mm using image's exif data. Then found f (in pixels) = 640*4.2mm/4.8mm = 560 pixels where 4.8mm was the Iphone SE's camera sensor width and 640 was the width of each down-sampled image ...

Features Detection & Matching

CV Project 1: Feature Detection and Matching Detector Design: My feature descriptor called manilsFeatureDescriptor is an extension of simple5x5featureDescriptor. Both manilsFeatureDescriptor and simple5x5featureDescriptor take gray-scaled input image(input) and reference to the feature set (output) as parameters. Both feature descriptor functions take a computed local maxima point using Harris corner detector algorithm and add some 'characteristics' to the detected feature points....
