Apparatus and method for smoothing regions and enhancing edges in gray scale images

摘要: An apparatus and method for enhancing image data elements used to form a gray scale are disclosed. The includes an adaptive neighborhood mask that is applied group of centered about selected pixel segregate the into center surround regions element or pixel. further modifies with weighting factors derive contrast vector in neighborhood. This compared smoothing window pair edge enhancement windows determine whether requires more clearly define surface edge, respectively. If enhancing, its value modified, otherwise it not modified. device performs this task each element. enhanced analyzed if possible and, so, process continues upon adjusted until maximized. area selector may enhance by selecting small at unterminated end detected image. adjusting changing restoring values their unenhanced values.
