Abstract
Hadamard matrices have been widely used in image processing. There are various constructions for Hadamard matrices: Kronecker product, Paley type I and II, Williamson type, etc. We investigate those of the Williamson type, and suggest a search algorithm for Hadamard matrices of the Williamson type. Using this we searched the Hadamard matrices of order 92. It took about 6.8 hours on a DEC Alpha PC. Based on the data for the order 92, we give an estimate for the exhaustive computer search for Hadamard matrices of Williamson type of order 428
