摘要： A method for identifying objects in a digital image includes tracing chain codes associated with the contour of the object; a series of states is maintained, and the next chain codes in the contour are accepted only if they comply with allowed chain codes for each state. Certain chain codes trigger a transition into a next state. If a disallowed chain code is encountered, the process halts.

摘要： Embodiments of the present invention provide for improved timing control in 2-D image processing to maintain a constant rate of memory fetches and pixel outputs even when the processing operations transition to a new line or frame of pixels. A one-to-one relationship between incoming pixel rate and outgoing pixel rate is maintained without additional clock cycles or memory bandwidth as an improved timing control according to the present invention takes advantage of idle memory bandwidth by pre-fetching a new column of pixel data in a first pixel block of a next line or frame while a new column of an edge pixel block on a current line is duplicated or zeroed out. As the edge pixel block(s) on the current line are processed, the data in the first pixel block of the next line or frame become ready for computation without extra clock cycles or extra memory bandwidth.
摘要翻译：本发明的实施例提供了二维图像处理中的改进的定时控制，以便即使当处理操作转换到新的像素或新的像素帧时，仍然保持恒定的存储器读取速率和像素输出。保持输入像素速率和输出像素速率之间的一对一关系，而不需要额外的时钟周期或存储器带宽，因为根据本发明的改进的定时控制通过预取一个新的像素数据列来利用空闲存储器带宽在下一行或帧的第一像素块中，而当前行上的边缘像素块的新列被复制或清零。当处理当前行上的边缘像素块时，下一行或帧的第一像素块中的数据就可以在没有额外的时钟周期或额外的存储器带宽的情况下进行计算。
