20150350666 | BLOCK-BASED STATIC REGION DETECTION FOR VIDEO PROCESSING - Methods, apparatus, systems and articles of manufacture to perform block-based static region detection for video processing are disclosed. Disclosed example video processing methods include segmenting pixels in a first frame of a video sequence into a first plurality of pixel blocks. Such example methods can also include processing the first plurality of pixel blocks and a second plurality of pixel blocks corresponding to a prior second frame of the video sequence to create, based on a first criterion, a map identifying one or more static pixel blocks in the first plurality of pixel blocks. Such example methods can further include identifying, based on the map, a static region in the first frame of the video sequence. | 12-03-2015 |
20150379666 | PIXEL-BASED WARPING AND SCALING ACCELERATOR - Technologies are presented that allow efficient pixel-based image and/or video warping and scaling. An image processing system may include a memory and an accelerator unit communicatively coupled with the memory. The accelerator unit may, based on configuration settings, receive, from a memory, at least a portion of an input image as an array of neighboring four-cornered shapes; and process each shape by: determining locations of an array of output pixels delineated by four corner locations of the shape via linearization; interpolating a value of each pixel of the array of output pixels; and storing the interpolated pixel values in the memory. For warping, the array of neighboring four-cornered shapes may include an array of neighboring distorted tetragons that approximate distortion of the input image, and the interpolated pixel values may represent a warped output image. For scaling, the array of neighboring four-cornered shapes may include an array of neighboring rectangles. | 12-31-2015 |
20160093029 | High Dynamic Range Image Composition Using Multiple Images - High dynamic range image composition is described using multiple images. Some embodiments relate to a system with a buffer to receive each of three different images of a scene, each image having a different amount of light exposure to the scene, as general purpose processor to estimate the alignment between the three images, and an imaging processor to warp the images based on the estimated alignment and to combine the three images to produce a single high dynamic range image. | 03-31-2016 |
