Detailed Description
Searches to minimise a cost of pixels in an arbitrary region.
Samples intensities in a region of interest, defined by the set of mbl_chords roi_. These are in the bounding box [0,roi_ni_)x[0,roi_nj_). These are optionally normalised, then fed into a mfpf_vec_cost function to evaluate the quality.

Search for local optima around given point/scale/angle.
For each angle and scale (defined by internal nA,dA,ns,ds) search in a grid around p (defined by search_ni and search_nj). Find local minima on this grid and return them in poses. Responses lie on grid in (x,y,ds,dA)
Note that an object in an image may lead to multiple responses, one at each scale and angle near to the optima. Thus the poses defined in pts should be further refined to eliminate such multiple responses.
