Apparatus, systems and methods for adaptively reducing blocking artifacts in block-coded video are disclosed. In one implementation, a system includes processing logic at least capable of deblock filtering at least a portion of a line of video data based, at least in part, on edge information and texture information to generate at least a portion of a line of deblocked video data, and an image data output device responsive to the processing logic.

Method and apparatus for adaptively reducing artifacts in block-coded video

Techniques are provided for detection and location of active display regions in videos with static borders. A methodology implementing the techniques according to an embodiment includes extracting features from rows and columns of pixels of a video frame. The features are based on horizontal gradient runs (HGRs) and vertical gradient runs (VGRs). The method also includes detecting one or more static regions of the frame, based on a comparison of differences between the features of the current video frame and features extracted from a previous video frame. The method further includes detecting one or more boundaries of the static regions based on a location of a maximum value of one of the features within the static region, if the maximum value is greater than a boundary detection threshold value. Determination of the active region in the current video frame is based on exclusion of the detected static regions.

A processor computes a measure of input image structural complexity of an input image, and searches a database of true positives to find one or more entries in the database that represent true positive images that are structurally similar to the input image. The processor compares a measure of signal quality of the input image and a measure of signal quality of one of the true positive images, as retrieved from the database, and based on the comparison updates a control variable that configures a signal quality conditioning process that is to be performed on the input image prior to processing of the input image by a computer vision processor thus improving performance of the computer vision task. Other embodiments are also described and claimed.

Control of computer vision pre-processing based on image matching using structural similarity

In some embodiments, color and contrast enhancement video processing may be done in one shot instead of adjusting one of color and contrast enhancement, then the other, and then going back to the first one to readjust because of the second adjustment. In some embodiments, global lightness adjustment, local contrast enhancement, and saturation enhancement may be done at the same time and in parallel. Lightness adjustment improves visibility of details for generally dark or generally light images without changing intended lighting conditions in the original shot, and is used to enhance the range of color/saturation enhancement. Local contrast enhancement done in parallel improves visual definition of objects and textures and thus local contrast and perceived sharpness.

Joint enhancement of lightness, color and contrast of images and video

Three-dimensional video is presented on a two-dimensional display. The view of the video is driven by user interaction. In one example, a two-dimensional (2D) video sequence in real time with a first view is synthesized from a video image sequence with depth captured by a first device. The 2D video sequence with the first view is provided to a second device in real time. A command is received from the second device to change a view of the 2D video sequence as the video sequence is rendered. The view of the 2D video sequence is changed as it is rendered to a 2D video sequence with a second view, and the 2D video sequence with the second view is provided to the second device in real time.

Techniques are disclosed to adaptively control an image sensor and image signal processor (ISP), collectively known as an image pipeline, such that a minimum amount of power is consumed by an electronic device while producing images that can be accurately analyzed by a computer vision application. The techniques disclosed herein can be implemented in various electronic devices capable of capturing and processing image data, such as, for example, smart phones, wearable computers, laptops, tablets, and other mobile computing or imaging systems. In an embodiment, the techniques disclosed herein are implemented in a system-on-chip device.

Techniques for context and performance adaptive processing in ultra low-power computer vision systems

Systems and methods may provide for the detection, location, and processing of static pixels during video processing. In one example, the method may include determining if a color component value of a pixel located at a pixel location remains constant between a first frame and a next frame, determining if the pixel is a low-difference pixel, calculating a motion-compensation error of the color component, determining if the motion compensation error of the color component is large, and generating a map of static pixels including the pixel.
