摘要： A camera using a programmable aperture is disclosed in which a programmable lens is disposed between a lens assembly and a sensor to properly transmit or block light rays reflected by a photographed object and incident to the lens assembly and then received by the sensor so as to obtain records of the incident light rays at different positions on the lens assembly. Moreover, complete light field data of the photographed object can be restored to facilitate subsequent image processing at any focal length.

摘要： A digital image stabilization method that integrates a digital stabilization device and a digital video encoder is disclosed. The digital stabilization device comprises a determining module for determining background regions, a comparison module for calculating motion vectors, and an adjustment module for adjusting jerky image motion in frames. When there are frame jiggles, the motion vector between an I frame and a P frame is used for motion estimation to get a first motion vector and also define a background region of the P frame. Next, a second motion vector of a B frame is calculated according to the background region to adjust jerky motion of the P frame and the B frame for stabilization. The next P frame then uses the background region of the preceding P frame as its background region.

摘要： A method and apparatus of tile-based belief propagation are disclosed. An image is split into a number of tiles. Messages are iteratively generated within each of the tiles based on the messages from neighboring pixels to the tile at a previous iteration, wherein each message represents information of a state of the pixel. The generated messages for sending out of the tiles are stored. Labels are then determined based on the stored messages, wherein each label represents the state of the pixel.

摘要： A low-backlight image visibility enhancement method and system is proposed for integration to a backlit type of display unit, such as active matrix LCD (Liquid Crystal Display). The proposed method and system firstly converts the image of each video frame into a brightness-based grayscale image; then decomposes the grayscale image into a low-pass base layer and a high-pass detail layer; and then performs a brightness compensation for the base-layer image and a contrast enhancement for the detail-layer image; and finally combines the two image layers into one single image and performs color conversion to the combined image. The resulted image is then used for display on the display unit. This feature allows the display unit to use a low level of backlight to save electrical power consumption while nevertheless allow the image to be displayed with good visibility.

摘要： In a method of realism assessment of an image composite, the foreground and the background are transformed into a color space, such as YCbCr, followed by projecting the foreground and the background to a subspace represented by the axes representing chromatic information. The image composite is assessed in the projected subspace, according to linearity of color distributions of the foreground/the background, or according to distance between the color distributions of the foreground/the background and a center of the transformed color space.
