摘要： An image processing apparatus and method may estimate binocular disparity maps of middle views from among a plurality of views through use of images of the plurality of views. The image processing apparatus may detect a moving object from the middle views based on the binocular disparity maps of the frames. Pixels in the middle views may be separated into dynamic pixels and static pixels through detection of the moving object. The image processing apparatus may apply bundle optimization and a local three-dimensional (3D) line model-based temporal optimization to the middle views so as to enhance binocular disparity values of the static pixels and dynamic pixels.

Each of the at least one second feature may correspond to one of the at least one first feature, and each of the at least one single-frame may be a previous frame of an initial frame of which the number of tracked second features is less than a threshold, among frames consecutive to multiple-frames.

摘要： A method and apparatus for processing a multi-view image are provided. A priority may be assigned to each hole pixel in a hole region generated when an output view is generated. The priority of each hole pixel may be generated by combining a structure priority, a confidence priority, and a disparity priority. Hole rendering may be applied to a target patch including a hole pixel having a highest priority. The hole pixel may be restored by searching for a source patch most similar to a background of the target patch, and copying a pixel in the found source patch into a hole pixel of the target patch.

摘要： An image processing apparatus and a method for enhancing depth are disclosed. The image processing apparatus may classify an input image into a foreground layer, a middle layer, a background layer, may calculate a representative color of each of the classified layers, and perform rendering of a color stereoscopy of the middle layer and a color stereoscopy of the background layer based on the representative color and a lightness of the background layer, thereby enhancing a stereoscopic effect and a depth. Also, a color temperature of the foreground layer and a color temperature of the middle layer are controlled based on the representative color and the background layer, to generate a difference in depth between the middle layer and the foreground layer, thereby representing an image having a more enhanced depth.
