【摘要】 在图像识别中经常需要对目标进行坐标变换，针对这种需要提出了一种以边界链码为基础的新变换算法，并讨论了它在与传统方法精度等同的条件下的运算量及其在实际应用中的参数确定方法．大幅度地提高了效率．更多还原

【Abstract】 Coordinate transformation is often used in medical image recognition. For this purpose a new transformation algorithm based on edge chain codes is developed, and the computation of parameters is also discussed. In contrast to traditional algorithm, it is accurate and efficient.更多还原
