Paper Abstract

The electric-carving printing ink cell image taken in complex lighting conditions with the traditional image processing algorithms can not be got the accurate edge information, so the feature data is not be accurately extracted. This paper use the improved P&M equation for ink cell image smoothing, while the eight-directions edge detection based Sobel is used for searching edge of ink cell, edge tracking algorithm make point of edge coordinate. These algorithms effectively reduce the influence of the unevenness light, accurately extract the feature data of the ink cell.
