Image warping
WitrynaImage warping Description. Image warping consists in remapping pixels, ie. you define a function M(x,y,z) -> (x',y',z') that displaces pixel content from (x,y,z) to (x',y',z'). Actual implementations rely on either the forward transformation M, or the backward (inverse) transformation M^-1. In CImg the forward implementation will go through all ...

Witryna1 maj 2024 · Forward warping still needs to apply backward warping locally, it is just an optimization to avoid having to buffer the entire source image. Just imagine the case that you want to "warp" an 1x1 image to an 1x2 rectangle. Whatever is done, transforming a single input pixel coordinate "0,0" obviously can't result in target coordinates "0,0" and ... WitrynaI'm trying to implement a homemade image manipulation tool using Python. Currently I'm trying to create an effect similar to GIMP's warp tool. Specifically, I'd like to try implementing the grow/shrink feature. This feature warps a region in the image, making it stand out or shrink in size. How wo
