    • An image segmentation apparatus, preferably integrally implemented in a device such as an FPGA, including a buffer memory for storing pixel data, a digital filter in communication with the buffer memory, the digital filter having programmable coefficients, a histogram generating module in communication with the buffer memory that generates a histogram of the pixel data, a statistics generating module in communication with the buffer memory that generates statistics regarding the pixel data, a threshold select module for selecting one of a plurality thresholds and an apply threshold module for applying the selected threshold to data stored in the buffer to generate exceedance data that exceed the selected threshold. In a preferred embodiment, a control module controls each of the buffer, histogram, statistics and threshold modules to control data flow, program filter coefficients and select the appropriate threshold.
    • 一种图像分割装置,优选地整体地实现在诸如FPGA的装置中,包括用于存储像素数据的缓冲存储器,与缓冲存储器通信的数字滤波器,具有可编程系数的数字滤波器,与 生成像素数据的直方图的缓冲存储器,与缓冲存储器通信的统计产生模块,其产生关于像素数据的统计信息;阈值选择模块,用于选择多个阈值中的一个;以及应用阈值模块,用于施加所选择的阈值 存储在缓冲器中的数据以产生超过所选择的阈值的超出数据。 在优选实施例中,控制模块控制缓冲器,直方图,统计和阈值模块中的每一个以控制数据流,程序滤波器系数并选择合适的阈值。
