Summary:
This paper presents a system that improves the recognition of primitives shapes and the complex shapes based on those primitive shapes. The shapes recognized are lines, poly-lines, circles, ellipses, arcs, curves, spirals, and helixes, and recognition was %98.56. It introduces two new features and a ranking system for shape recognition. The two new features are NDDE ( Normalized Distance between Direction Extremes ) and DCR ( Direction Change Ratio ). NDDE measures the length between the smallest and greatest direction values ( change in y over change in x ) and DCR is the ratio between the max change in direction over the average change in direction.

what about your thoughts I don't understand also what as your opinion on how it got the features?
