Fig. 1From: Real-time CUDA-based stereo matching using Cyclops2 algorithmComputation of kernels. a Example of a dense kernel. b Example of a sparse kernel. Each square in this figure corresponds to a value in the array that contains deltas. The red (darkest) square indicates the current position at point y, x for which a weight function value is being calculated. The frame that has several coloured squares in it is a kernel. These squares that belong to the frame, i.e. kernels, are considered when calculating the weight function value at point y, xBack to article page
