Abstract
A method, a device, and a computer program product for background image replacement in image data. The method includes receiving, from at least one image sensor of a device, frame data. The device generates a first depth map based on the received frame data. The device generates first foreground image data and first background image data, based on the first frame data and the first depth map. The method further includes determining a least used color in the first foreground image data. The least used color is identified as a first background color. The method also includes generating modified frame data by replacing the first background image data with the first background color and storing the modified frame data to a memory of the device.
