Hello,
I am playing with DLIB and face detection. After some try I saw a different ROI return by detector.
If load the image with OpenCV (it is a tiff image)
image = cv::imread(imagePath[imageId], CV_LOAD_IMAGE_COLOR);
then apply a clahe in this way
double clipLimit = 4.0f;
Size tileGridSize(8, 8);
Ptr<CLAHE> clahe = cv::createCLAHE(2.0, tileGridSize);
clahe->apply(gray, output);
and search for a face, detector returns image on the left.
If I load the image in the same way, but without apply clahe (or equalizeHist), detector returns ROI on the right side.
Am I missing something? My preprocessing is not the right thing to do? This is not the only case (in this case KA.FE4.48.tiff), also some other image from JAFFE dataset show the same result.
Thanks.
