Abstract
Since omnidirectional images contain many circular arc segments, radial directional processing for detection of certain features in the image is more appropriate than horizontal or vertical directional processing, as with usual rectangular images. Computation of the proposed radial processing algorithm is based on the well-known Bresenham raster algorithm for line drawing in discrete integer space, and thus it is very fast and efficient. Experimental comparisons between the proposed algorithm and conventional horizontal processing in terms of feature detection and computational efficiency are presented.
