Problems about accelerating the speed of inference stage about pico

[nenadmarkus]

I think you have a problem in the following line: int_luts[i][j] = (int)(*(&luts[0][0]+i*1024+j)*PERCISON);. Why not simply use int_luts[i][j] = (int)(luts[i][j]*PRECISION);? (I didn't put too much thought into this so I might be wrong.)

The offset variable tells us how much memory we have to skip in order to get to the next tree (ptree is a pointer to its beginning).

We use the line tcodes = ptree - 4; because idx starts from 1, as you can see from the code. This simplifies the j-based for loop that iteratesd over the individual binary tests contained in the tree.

thanks.
I'd like to know more about the meaning of matrix "tcodes ,lut ,thr" and their space relationship with pixel matrix.
What will happen if the pixel matri I fed into the function is smaller than the trainning period?
