Abstract: Disclosed is a musical instrument simulator executable on a portable computing device to cause the portable computing device to: display a first interface defining a plurality of keys and at least one key modifier; and generate a target sound in response to a user manipulation of one or more of the plurality of keys and the at least one key modifier.

Abstract: A method and system for detecting a target which uses composition correlation filters with score reaffirmation post processing for acquiring a target. The method and system uses target decision rules that are based on comparing the dot products, or peaks, of three score reaffirmation filters and their registered LADAR image to detect a target.

Abstract: A computer software program for replacing drop-out pixels and erroneous re values in the range channel of a laser detection and ranging system with a median pixel value in a moving square window centered about a pixel being processed whenever a co-registered intensity pixel value in the intensity channel falls below an intensity threshold. During the processing of each range pixel of the target, the computer software program will not alter the range value of the pixel if its corresponding intensity pixel has an intensity value above the intensity threshold. When the intensity value of the corresponding intensity pixel is below the threshold, the intensity guided filter replaces the range value with the median value of all the "good" pixels within a moving window the size of a kernel having X and Y dimensions. This results in the intensity guided filter smoothing out noisy pixels in the range channel of while retaining edge pixel values for the image.
