Superpixel-based refinement of low-resolution foreground segmentation

A non-transitory computer readable storage medium having a program recorded thereon, the program being executable by a computerised apparatus to perform foreground/background segmentation of an input image, said program comprising:

• code for receiving a first foreground segmentation at a first resolution of the input image;
• code for determining a plurality of seed points based on a location of the foreground segmentation of the input image;
• code for 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
• code for 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.

A computerised device to perform foreground segmentation of an input image, said device comprising:

• a memory for storing a computer program;
• a processor coupled to the memory for executing the computer program, the computer program comprising instructions for:
• receiving a first foreground/background segmentation at a first resolution of the input image and for storing the input image in the memory;
• determining a plurality of seed points based on 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 labelled seed points to obtain a second foreground segmentation of the input image;
• 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;
• and
• displaying at least one of the segmentations on the display.
