Abstract: A method for capturing digital images of friction ridge prints from the fingers/palms of a subject that have acceptable quality. The method includes a livescan device; a means of obtaining digital images of inked prints; and a software program that captures and stores print images and evaluates their quality. Fingerprint/palmprint images to be submitted to databases must be of suitable quality for automated fingerprint/palmprint identification software. There are sometimes problems capturing prints of suitable quality when using livescan devices. If a livescan image quality is below a threshold, the program prompts the user to produce an inked version of the same finger/palm on a substrate and then scan or digitally photograph the inked print impression. The program evaluates the quality of the digital inked image. If the quality exceeds the threshold the image is selected for submission to the database.

Abstract: A rock fragmentation analysis system is provided for analyzing blasted rock (or other fragmented particles) to assess quality of a blast for efficient processing of subsequent operations in a mine, a quarry, etc. The system includes a hardware system and an image processing system. The hardware system includes a camera and a lighting system. The lighting system illuminates an area of the mine, quarry, etc. where a load haul dump (LHD) vehicle passes through. Once the LHD vehicle passes through the illuminated area, the camera provides video signals of scoop-top view images of the LHD vehicle to the image processing system via known communication means, such as hard-wired and wireless. The image processing system receives the video signals, captures the scoop-top view images, evaluates the images for subsequent fragmentation analysis, and performs the rock fragmentation analysis. The image processing system performs these functions using several software modules.
