Abstract :
Images consisting of dots on a blank background may contain obscure collineations. Transformation of the dots into reciprocal polar lines is effective in detecting sporadically-spaced alignments. The implementation presents polar lines by discrete pixels which compose a cumulative real-valued matrix suited to visual grey-scale presentation.
