0 a picture or pattern that is broadcast so that the quality of the television picture received can be examined and improved if necessary by using the controls on the equipment -- 测试图案（电视台播放的图片或图案，用于检测或改进图像质量）
The best performance is for character "1" which, even at 50% test pattern noise, was correctly classified more than 50% of the time.
For example, in the second test pattern set, r was set to 5% for all example images rather than being ranged from 0% to 5%.
Ronchi test patterns are matched to those of standard mirrors or generated by computer.
Eleven networks were trained, one per training pattern set, and tested on all 11 test pattern sets.
Sequential automatic test pattern generation by constraint programming.
This test generates 21 test patterns and runs for 15 minutes.
It is used for refining both the test circuitry and the test patterns iteratively, until a satisfactory fault coverage is obtained.
In a cross-adaptation experiment, we explored the possibility that differences in the temporal frequency of adapting and test patterns played a role.
