Picture area identifying device
专利汇可以提供Picture area identifying device专利检索，专利查询，专利分析的服务。并且PURPOSE: To reproduce the picture of high quality by executing a contour detec tion processing to a binarized picture and executing an edge detection processing to an original picture, and deciding a character area if the detected contour component exists at a point near the edge detected area.
CONSTITUTION: A binarizing means 1 binarizes an input picture including the character line and halftone pictures, and a contour detecting means 2 detects the contour of the binalized picture. An edge detecting means 3 detect the edge of an original picture. An area deciding means 4 decides a character area if the contour component detected by the means 2 exists at a point near the edge area detected by the means 3. Otherwise the relevant noted picture is decided as a non-contour part and an accurate contour is obtained to the original picture.
