Can you provide more context, please? What is your environment looking like? C++ or Python? Do you have OpenCV as well as opencv_contrib installed/built? Which file do you see the...

Can you provide some description about your environment (SW and HW), please? Is the video maybe decoded using a SW-decoder because no HW-accelerated video decoding available in HW or no...

Sounds interesting!

Please have a look at the API's documentation, e.g. here: https://docs.opencv.org/3.4/dc/d6b/group__video__track.html#ga1aa357007eaec11e9ed03500ecbcbe47 > Unlike findHomography and estimateRigidTransform, the function findTransformECC implements an area-based alignment that builds on intensity similarities. In essence,...

It could depend on the image content. It could be that your image requires another stopping criteria - to let the algorithm converge "later"? Have you "visually" checked your input...

If you check the OpenCV documentation, e.g. for OpenCV in version v4.4.0 here: "https://docs.opencv.org/4.4.0/de/daa/group__xphoto.html#ga51a091aa54e26b3546316ce2c1df190b" the "namespace" looks like this: retval = cv.xphoto.createTonemapDurand( [, gamma[, contrast[, saturation[, sigma_color[, sigma_space]]]]] ) Are...

Can you provide more details and pointers about which sample and which problem you are talking about? What have you tried so far? Were you following a specific post, specific...

There is a " blog post " mentioned, pointing to "https://learnopencv.com/face-morph-using-opencv-cpp-python/". In the section "1. Find Point Correspondences using Facial Feature Detection" the following is mentioned: > I used dlib...

Some samples have their own license information, like (from Google-search): - https://github.com/spmallick/learnopencv/blob/master/UI-cvui/LICENSE.md - https://github.com/spmallick/learnopencv/blob/master/Colorization/LICENSE I found a screenshot of the license shown when installing OpenCV (with the samples): https://learnopencv.com/installer-license/ But...

Your referenced article says these: > But it is very easy to find a few point correspondences. For morphing two dissimilar objects, like a cat’s face and a human’s face,...
