Abstract
This article reports on the application of computer vision techniques, implemented on an IBM PC‐compatible machine, as a means of obtaining morphometric characterization of neural cells. The features considered include projection polar histograms, orientation polar histograms, and the determination of the convex hull of dendritic (or axonal) arborizations. As will be discussed in this work, the Hough transformation technique has proven to be of great help for the determination of all the above‐mentioned parameters. Two actual application examples respective to the analysis of retinal ganglion cells are also presented and discussed.
