opencv_gpu module is too big to distribute it as is with OpenCV Manager, so it is designed to be linked statically. It allows to cut all unnecessary functions in link time to decrease size of native libraries. Opencv_gpu module depends on CUDA runtime library and some CUDA-accelerated mathematical libraries like NPP and CUFFT.

  • Pixels are weighted using contrast, saturation and well-exposedness measures, than images are combined using laplacian pyramids. The resulting image weight is constructed as weighted average of contrast, saturation and well-exposedness measures.

If any histogram bin is above the specified contrast limit (by default 40 in OpenCV), those pixels are clipped and distributed uniformly to other bins before applying histogram equalization. After equalization, to remove artifacts in tile borders, bilinear interpolation is applied. Below code snippet shows how to apply CLAHE in OpenCV:All incoming files are processed via OpenCV and analyzed with Tensorflow. That was the part that needs proper tuning of the software according to the hardware. As you may understand, in the countryside, you won't be keeping the beefy server running, so you need to squeeze the most from the equipment you can afford.

OpenCV has a function to do this, cv.equalizeHist. Its input is just grayscale image and output is our histogram equalized image. So now you can take different images with different light conditions, equalize it and check the results. Histogram equalization is good when histogram of the image is confined to a particular region.

CLAHE (Contrast Limited Adaptive Histogram Equalization) In adaptive histogram equalization, image is divided into small blocks called "tiles" (tileSize is 8x8 by default in OpenCV). Then each of these blocks are histogram equalized as usual.
