Now, the full cycle (fetch image, process it and publish the position of the object) takes about 130 milliseconds. So far we did only 2 simple optimizations = perform filtering at the level of the color map + replace costly color conversion at each pixel access with simple access to raw pixel values. Hopefully we can do better. After less than an hour optimizing the code, we have improved performance with a factor of 5.
