When one is speaking, lips change regularly. Therefore, Lip contour extraction is very meaningful. In this paper, for lip color images, this paper extracts lip contour by means of the RGB-based improved region growing algorithm. Through RGB three components, the relationship between color from and adjacent pixels is calculated. According to certain rules,(More)
To solve the problem of extracting the features of green fluorescent protein image, this paper proposes a method of combining a HSV model with watershed algorithm. This article based on the HSV color model, make full use of the color and brightness of image, by setting the brightness of the threshold to deal the image with binarization processing, then(More)
