Title
(EN) Image segmentation method and apparatus
(ZH) 一种图像分割方法及装置
Abstract
(EN)
The invention, which is suitable for the field of the image processing technology, provides an image segmentation method and apparatus. The provided image segmentation method comprises the following steps that: a sliding operation is detected and a closed curve encircling a target image is generated at an original image according to the sliding operation; a binaryzation image template is generated based on the closed curve, wherein the size of the binaryzation image template is equal to that of the original image; according to the generated binaryzation image template, detection is carried out and the contour of the target image is obtained; a mask is generated according to the contour of the target image; a transparency value of an unknown zone in the mask is calculated; a foreground component and a background component of the original image are determined by utilizing the transparency value and the original image; and on the basis of the determined foreground component and background component of the original image, a foreground image is obtained by segmentation from the original image. According to the invention, the operation feature and the processing performance of the mobile terminal are fully combined; and image segmentation can be realized effectively at the mobile terminal.
