The Hough transform (Hough, 1962) has been used to characterize analytic features. It was first applied to the recognition of straight lines, and later extended to circles, ellipses and arbitrary shaped objects. Its main disadvantage is the computational and storage requirements increase as a power of the dimensionality of the curve. It is not difficult to(More)
The increase of array size and decrease of cell size make the testing of infrared focal plane array (FPA) being difficult. A design for test scheme, cross-check test, for infrared focal plane array (FPA) is presented in this paper. For an array size of M by N, the testing times can be reduced from the order of M*N to M+N. Analysis on the fault detectability(More)
