Title:
適応的前景マスクアップサンプリングに基づく一連のカラー画像フレームのオブジェクトセグメンテーション
Document Type and Number:
Japanese Patent JP7015017
Kind Code:
B2
Abstract:
An image processing apparatus includes a first type of sensor, a second type of sensor, and a control circuitry. The control circuitry receives a first foreground mask for an object-of-interest in a previous color image frame and further estimate a second foreground mask for the object-of-interest in a current color image frame at a first image resolution. The control circuitry further upsamples the second foreground mask to a second image resolution and select at least one region-of-interest in the current color image frame. The control circuitry then upscales the upsampled second foreground mask by an expectation parameter generated based on a kernel density-based estimation for the at least one pixel in a selected region-of-interest. The upscaled second foreground mask exhibits a minimum foreground mask error that is caused by upsampling with respect to the estimated second foreground mask.
