摘要
彩色合成选择法是根据色度学原理,求出地物之间在各种彩色合成方案中的色差,以选择彩色合成方案。将此方法应用到黄河入海口,提取黄河水、海水、沙滩、陆地等主要地物信息,效果明显。
Color composition is simple and useful in image enhancing processing, but is always limited by user's experence. In this paper a metho of choosing color composition is given which is based on chromaticity. The visual sensitivity to color difference between objects on computer VDP can be caculated in all kinds of possible color composition, then the best choice of color composition can be gained. It is very profitable to apply this method to extract interesting information from images. In Huanghe River mouth there are about four kinds of objects such as Yellow Sea water, Huanghe Water, delta Land and seabeach which basicly determine the enviromental changes and influence the oil industry development. Using Thematic images and choosing best color composition has successfully define the boundaries between objects and provides exact data for further studies.
