Abstract: A video encoder is provided for use with first still image data, second still image data and third still image data. The video encoder includes a determining portion and a frame generating portion. The determining portion can output a determining signal based on the second still image data and the third still image data. The frame generating portion can output an encoded signal having first frame data, second frame data and third frame data. The first frame data is based on the first still image data. The third frame data is based on the first still image data and the third still image data when the determining signal is less than a predetermined threshold. The third frame data is not based on the first still image data when the determining signal is equal to or greater than the predetermined threshold.

Each node includes classifiers for classifying the objects as a positive object and a negative object. The positive object and the negative object classified by the parent node in each layer are further classified by one or more operatively linked child nodes in the subsequent layer.

Abstract: Systems and methods for decoding of compressed video enable the storing of compressed video data in a memory shared by a group of symmetric multiple processors. The video includes a plurality of frames and each of the plurality of frames has one or more slices. Such one or more slices are assigned, by a main processor, of the group of symmetric multiple processors to the group of multiple processors. The one or more assigned slices are partially decoded by the one or more of the group of multiple processors and the partially decoded one or more slices are stored in the memory. Subsequently, each of the plurality of frames having at least one partially decoded slice is assigned to one or more of the group of multiple processors. In a successive progression, the group of multiple processors in combination fully decodes each of the plurality of frames.

Abstract: Disclosed is a method for correction of pixel values of an input image to compensate for variation in image capturing conditions is proposed. In an embodiment, the method enables computing a statistical value from a selected set of pixel values associated with the input image. Based, at least in part, on the computed statistical value a set of parameter values is derived. The parameter values correspond to at least two gompertz functions. The method further enables applying the at least two gompertz functions to the input image to obtain an output image. This results in an output image with one or more corrected pixel values.

Abstract: Systems and methods are disclosed for generation of a panoramic image of a scene. In an implementation, the method includes acquiring a plurality of images (e.g. first image and a second image) of the scene. Subsequent to image acquisition, the plurality of images is registered based on spatial relations of image data in an overlap region between the images. The spatial relations may correspond to distance and angle between a plurality of features in the first and the second images respectively. The registered images are merged based at least in part on a block based mean of the overlap region to generate the panoramic image. Block based merging is utilized to normalize spatially varying intensity differences of the first image and the second image.
