Abstract: A system for processing video. The system may include a video camera, a processing unit, and a video display, the video camera being configured to generate a plurality of consecutive luminance frames, including a last frame and a plurality of preceding frames. The processing unit may be configured to: shift the plurality of preceding frames, to register the preceding frames with the last frame to form a plurality of shifted frames, take a Fourier transform of each of the plurality of frames, to form a corresponding plurality of initial Fourier transform frames, iteratively update the plurality of Fourier transform frames by, on the (n+1)th iteration of a plurality of iterations, replacing each Fourier transform frame with a linear combination of the Fourier transform frames of the nth iteration, the Fourier transform frames of the 0th iteration being the initial Fourier transform frames.

Abstract: Technology is described for creating time multiplexed, high dynamic range images. The method can include the operation of obtaining a first image having a base exposure level captured from an image sensor. The first image can be stored in an accumulation memory. Another operation is obtaining a second image having a modified exposure level as compared to the base exposure level. A determination can be made as to whether incoming pixels in the second image exceed a saturation threshold. The pixels of the second image can be combined with the pixels of the first image to form a high dynamic range image in the accumulation memory.

Abstract: Systems and methods are described for generating a monochrome image from a color filter array. Image data from an image capturing device may be received having a color filter array comprising a plurality of filter positions. The image data may be interpolated to de-mosaic the image data into three sets of data representing red, blue, and green (RGB) data, respectively, for each of the plurality of filter positions. A weight may be calculated for each value of the RGB data based on a local gradient calculated for each value of the RGB data. A pixel value may be calculated for each pixel position for generating a monochrome image using the weight for each value of the RGB data.

Abstract: In systems and methods disclosed herein, a transform may be determined for a given target object and background in an image between a native color space of the image and a second multi-dimensional color space representing a preferred color space for a tracker. The transform may then be applied to convert a plurality of pixels in the imaged scene to the second multi-dimensional color space thereby advantageously increasing a perceived contrast by the tracker between the target object and the background.
