Abstract: A computer vision system is provided that includes a camera capture component configured to capture an image from a camera, a memory, and an image compression decompression engine (ICDE) coupled to the memory and configured to receive each line of the image, and compress each line to generate a compressed bit stream. To compress a line, the ICDE is configured to divide the line into compression units, and compress each compression unit, wherein to compress a compression unit, the ICDE is configured to perform delta prediction on the compression unit to generate a delta predicted compression unit, compress the delta predicted compression unit using exponential Golomb coding to generate a compressed delta predicted compression unit, and add the compressed delta predicted compression unit to the compressed bit stream.

Abstract: A Convolutional Neural Network (CNN) based-signal processing includes receiving of an encrypted output from a first layer of a multi-layer CNN data. The received encrypted output is subsequently decrypted to form a decrypted input to a second layer of the multi-layer CNN data. A convolution of the decrypted input with a corresponding decrypted weight may generate a second layer output, which may be encrypted and used as an encrypted input to a third layer of the multi-layer CNN data.

Abstract: Several systems and methods for processing of video frames based on one or more video formats are disclosed. In an embodiment, a video processing system comprises a memory and a video engine. The memory stores a plurality of video frames, a primary set of instructions and a plurality of secondary sets of processing instructions. Each secondary set of processing instructions is associated with a video format. The video engine is loaded with the primary set of instructions and is configured to fetch one or more video frames and a secondary set of processing instructions from the memory based on the loaded primary set of instructions. The fetched secondary set of processing instructions corresponds to a video format determined for processing of the one or more video frames. The video engine performs processing of the one or more video frames based on the secondary set of processing instructions.

Abstract: A VP8 video decoder is implemented by partitioning the required functions across multiple sub systems, with an optimal mapping to existing functional blocks. Key optimizations include the reuse of hardware designed for prior generation VP6 and VP7 decoders. In order to reduce implementation complexity, cost and power consumption, a non-exact, approximate deblocking loop filter is implemented.

Abstract: A method for analyzing images to generate a plurality of output features includes receiving input features of the image and performing Fourier transforms on each input feature. Kernels having coefficients of a plurality of trained features are received and on-the-fly Fourier transforms (OTF-FTs) are performed on the coefficients in the kernels. The output of each Fourier transform and each OTF-FT are multiplied together to generate a plurality of products and each of the products are added to produce one sum for each output feature. Two-dimensional inverse Fourier transforms are performed on each sum.
