Optimizing compilers have become an essential component in achieving high levels of performance. Various simple and sophisticated optimizations are implemented at different stages of compilation to yield significant improvements, but little work has been done in characterizing the effectiveness of optimizers, or in understanding where most of this improvement comes from.

The Mt. Wilson synoptic program of solar magnetic observations carried out at the 150-foot tower scans the solar disk one to twenty times per day. As part of this program, the radius is determined as an average distance between the image center and the point where the intensity in the FeI line at 525:0nm drops to 25% of its value at disk center. This record extends back to 1967. We have carried...

The task of face detection in a single image is to detect the existence of human face in an arbitrary image and show the location if faces exist.
