Create Templates from Feature Homography
Hello,
Currently i am working on texture tracking.
Presently, i have extracted AKAZE features and matched them to the known image Ids.
Each of these points can be of any size/orientation depending on how the texture is viewed by the camera.
1) Known homography from features 2) Original texture
How can i warped an NxN window around each feature point in the original image?
This sample shows how to match between source image and scene. https://docs.opencv.org/2.4/doc/tutor...
I would like to make a template for each point in the source image to match to the video image. Assuming the texture won't move again, we want to warp each feature to get a NxN template for that feature.
I don't think you can use an ROI as the feature's location in the original image is important when using homography.
Psuedo Code
For each feature point
Create a template from original image
Warp template, using the homography, to get a template as it "SHOULD" be in the camera view for
better match.
The issue i am having is that I do not wish to warp every pixel in the source image for each template.
How to do this the smart way?? Efficiently?
Regards,
Daniel
