To reduce the storage volume of the test data during the built-in self-test (BIST), a new BIST technique based on two dimensional compression of test data is presented.

为压缩内建自测试(BIST)期间所需测试数据存储容量，提出了一种新的基于测试数据两维压缩的BIST方案。

This algorithm is based on high-order range model, which firstly corrects range walk in the process of range compression and then corrects range bending in two dimensional frequency domain.

该算法基于高阶距离模型，首先在距离压缩时校正距离走动，然后在两维频域校正距离弯曲。

At the same time, we introduce a kind of two dimensional inverse heat conduction problems which do not convect with outer space in doing the compression, and we have got the expected result.

同时将一类与外界无热交换的二维逆热传导方程应用到图像压缩中，并取得了预期的效果。
