Linear combination of two matrices
Test suite for algebra.cl -- Linear combination OK
Linear combination OK
Kernel for gradient computation OK
Working on max/min detection -- TODO: write unit test
flipped arguments order: image size and kernel size in convolution
kernels. Updated tests accordingly
Gradient norm/orientation and MinMax detection working
Do not use constant memory for large images - Implementing edge response detection
Merge remote branch 'pierre/master'
Plan is able to calculate all blurs & DoG on the GPU
