摘要： A method for automatically determining the region of interest from an image comprises the three steps of (a) analyzing content of the transformed coefficients of an image after a discrete signal transformation and partitioning an image into the interested region and background region that are based on p×p-pixel sub-blocks for performing classification; (b) locating the central point of the interested sub-blocks; and (c) integrating a plurality of the interested sub-blocks from said central point to the boundary of an image to generate a closed and continued region of interest by using a image processing technique with considering the bit-rate requirement.

摘要： An arithmetic device with low power consumption includes master latches, a dynamic range detection unit, slave latches, an operation unit, and a word-length restoration unit. In the arithmetic device, the master latches latch a plurality of (such as two) input data. The dynamic range detection unit detects the effective dynamic range of these input data. The slave latches latch the values of the effective dynamic-range bits of these input data. The operation unit performs predetermined operations of the bits of these effective dynamic range to obtaing an operation result. Since the operation unit only performs operations of the bits of the effective dynamic range, the circuit corresponding to other bits will not demonstrate switching of power consumption, thereby lowering the overall power consumption. Furthermore, the word-length restoration unit will complement the operation result to its original output length in association with the sign of the operation result, for obtaining the correct operation result.
