| 发明名称 | Superpixel-based refinement of low-resolution foreground segmentation | ||
| 摘要 | A computer-implemented method performs foreground segmentation of an input image. The method receives a first foreground segmentation at a first resolution of the input image and determines a plurality of labelled seed points based on the first foreground segmentation of the input image. The method associates each of the plurality of pixels in the input image with one of the determined labelled seed points to obtain a second foreground/background segmentation of the input image, and performs foreground separation on the input image at a second resolution by classifying each of the segments of the second segmentation as one of foreground and background based on the label of the associated seed point. | ||

| 主权项 | 1. A computer-implemented method of performing foreground/background segmentation of an input image having a plurality of pixels, said method comprising: receiving a first foreground segmentation at a first resolution of the input image; determining a plurality of seed points based on a location of the foreground segmentation of the input image; associating each of the plurality of pixels in the input image with one of the determined seed points to obtain a second foreground segmentation of the input image; and performing foreground separation on the input image at a second resolution by classifying each of the segments of the second segmentation as at least one of foreground and background based on a label of the associated seed point. | ||
