A method for image/video segmentation, capable of segmenting an image signal for obtaining plural texture color feature regions, by utilizing both of the advantages carried by the texture feature and the color feature is disclosed. The method comprises the following steps: (A) receiving an image signal including plural image pixels; (B) executing a Gabor filtering process and a value operation process on each of the plural image pixels; (C) designating each of the plural image pixels a corresponding texture feature vector basing on the result of the value operation process; (D) executing a segmentation process on the image signal basing on the texture feature vector of each of the plural image pixels, for obtaining plural texture feature regions; and (E) executing a re-segmentation process on plural color feature regions basing on the distribution of the plural texture feature regions, for obtaining plural texture color feature regions.
