A Review: Improvement of Segment Distance Ratio Method for Arabic Contour Data Approximation

Contour compression plays critical role in image processing applications. In this work we introduce a new version of Segments Distances Ratios (SDR) approach for contour approximation. At the beginning, the contour is extracted by an approach called single step parallel contour extraction (SSPCE). The main benefit of the modified version is that can gives more quality compared to the previous one by about 10 and 4 decibels, with compression ratio equals to 60% and 90% for single and multi-contours respectively. However the performed time almost the same for both algorithms. Finally, the discussion of the efficiency and the performance for the analyzed method is introduced.
