function frameStretcher(cameraImage,peakMap)

%% Rotation correction: This corrects the rotation of the grid peaks w.r.t the camera frame
% When overlaying two images: camera and heatmap, the heatmap pixel#1
% should correspond to left bottom and pixel#29 should correspond to left
% top. This rotation takes care of that.
% The transformation is essentially flipping in vertical and horizontal both and then taking a transpose.
% This approach is better than changing the original peakMap because the
% original peakMap preserves the pixel identity also as 'ij' address.

peakMapFT = (rot90(peakMap,2))';
