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.
