摘要： A scalable rank filter and method for performing rank filtering are disclosed. In one embodiment, the rank filter comprises a W staged pipeline with W stages to receive N input data samples and operable to generate an output based on the N input data samples as a result of the W stages completing execution, where W is a bit length of the inputs and W and N are integers greater than two; and output logic coupled to the W staged pipeline to determine the output prior to all W stages completing execution and to output the median.

摘要： A mechanism is described for facilitating hybrid tone mapping in camera systems according to one embodiment. A method of embodiments, as described herein, includes detecting a scene having a sequence of frames, and fusing the sequence of frames into a fused raw frame. The method may further include reconstructing the scene by performing global tone mapping and local tone mapping on the fused raw frame, and outputting an image reflecting the reconstructed scene based on the tone-mapped raw frame.

摘要： Techniques related to temporal noise reduction of images are discussed. Such techniques may include generating a noise stream corresponding to an input image and adaptively re-combining the noise stream with a reference image corresponding to the input image and a spatially noise reduced image corresponding to the input image to generate a temporal noise reduced output image.

摘要： A mechanism is described for facilitating histogram and entropy-based texture detection in computing systems, according to one embodiment. A method of embodiments, as described herein, includes detecting an image of a scene, and computing multi-scale local binary pattern (LBP) image for the detected image based on a noise model associated with the detected image. The method may further include calculating a local histogram based the multi-scale LBP image, and calculating LBP entropy based on the local histogram. The method may further include applying a threshold to convert the LBP entropy into textureness of a texture map of the detected image for processing by an image signal processing (ISP) engine.
