A Hough based motion detection image recording system includes an image sensor operable to view a surveillance site and output real-time image data corresponding to the site. The system also includes a processor operable to receive the image data from the image sensor and a memory coupled to the processor. The system includes a transformation application residing in the memory and executable by the processor. The transformation application is operable to detect a real-time feature segment associated with the site from the image data. The system further includes an analysis engine residing in the memory and executable by the processor. The analysis engine is operable to compare the real-time feature segment with a baseline feature segment and initiate recording of the image data if the feature segment comparison exceeds a predetermined criteria.
摘要:
The proposed architecture is integrated onto a Digital Signal Processor (DSP) as a coprocessor to assist in the computation of sum of absolute differences, symmetrical row/column Finite Impulse Response (FIR) filtering with a downsampling (or upsampling) option, row/column Discrete Cosine Transform (DCT)/Inverse Discrete Cosine Transform (IDCT), and generic algebraic functions. The architecture is called IPP, which stands for image processing peripheral, and consists of 8 multiply-accumulate hardware units connected in parallel and routed and multiplexed together. The architecture can be dependent upon a Direct Memory Access (DMA) controller to retrieve and write back data from/to DSP memory without intervention from the DSP core. The DSP can set up the DMA transfer and IPP/DMA synchronization in advance, then go on its own processing task. Alternatively, the DSP can perform the data transfers and synchronization itself by synchronizing with the IPP architecture on these transfers. This architecture implements 2-D filtering, symmetrical filtering, short filters, sum of absolute differences, and mosaic decoding more efficiently than the previously disclosed architectures of the prior art.
