Abstract:
1. A system for performing an image search procedure with an electronic device, comprising: image data stored in a memory device that is accessible to said electronic device, said image data including a query image and test images; and a feature detector that calculates image parameters corresponding to said image data, said feature detector utilizing said image parameters to calculate distance values that represent texture similarity characteristics between said query image and said test images, said feature detector evaluating said distance values to determine a matching image from among said test images, said image parameters including coefficient mean absolute values for each of said subbands, a coefficient mean absolute value μ for a subband LH being calculated utilizing a formula: where LH(i) is said subband LH at a level i, W is a wavelet coefficient, m is a coefficient row, n is a coefficient column, M is equal to a total number of coefficient rows, and N is equal to a total number of coefficient columns.
