Hi, I also think that the linear kernel should be faster then gaussian. However, the computation of these kernels is probably negligible to the other parts (FFT, ...) so the fps is basically the same. If you are really interested in answer, you can do some code profiling to measure how much time is actually spend in the kernel computation w.r.t. the rest of the code, which should give you the answer.
I run the code 2 times(one using linear kernel, another using gaussain kernel) in OTB50, every setting is same except the kernel. The results are ,the tracking speed of using linear kernel is 236fps, and the tracking speed of using gaussain kernel is 234fps. In theory, the speed of using linear kernel is faster than using gaussain kernel.
