Abstract
Locations of respective image frames contained on an image recording, such as a continuous color photographic film strip scanned by digitizing opto-electronic scanner are identified by storing scanline data produced by the scanner in a digital database, and processing the stored scanline data to generate a predictor space which is used to identify locations of all the minimally valid frames. Thereafter, the well formed image frames are used to produce statistics which are used to detect the location of other frames.
