Embodiment Construction
[0059] refer to figure 1 , a target saliency detection method for rainy images proposed by the present invention includes the following steps:
[0060] S1. Extract the visual saliency based on brightness and color features, and calculate the brightness saliency map S lc .
[0061] S2. Extract the visual saliency based on the color difference feature, and calculate the color difference saliency map S cv .
[0062] In the prior art, it is commonly used to obtain the contour saliency of the image by detecting the difference in the contour, however, there is still a certain gap for color images. Part of the color information in rainy images will be annihilated by raindrops, but the remaining color information can also determine the saliency detection of the image. For example, for a rainy image, the difference saliency of the image can be calculated using the absorption time of the absorption Markov chain on the color domain.
