An obstacle in old document interpretation comes from the lack of image quality. Old documents frequently appear with digitization errors, uneven background, bleed-through effect. A new approach based on morphological color operators to restore the color text is presented. The morphological tools are based on three color spaces, HSI well known in morphological processes, YCrCb and YIQ rarely used...
The method on Camellia Oleifera segmentation is discussed in this article. To reach this goal, two major factors need to be considered :(1) the different color between Camellia Oleifera and its background (2) the similar color between Camellia Oleifera and its background. This paper outlines an image processing method for segmenting Camellia Oleifera from its background. To the former, color factor...
Multivariate mathematical morphology is increasing becoming a powerful utility for color image processing and analysis. In the paper, a new vector ordering scheme based on distances in the HSI color space is proposed. The methodology first uses nonlinear weighted combination with color distances, where vectors are reduced to scalars with the help of weighted coefficients. These coefficients are entirely...
