| Number | Title | Issue Date |
| 6549674 | Image compression based on tiled wavelet-like transform using edge and non-edge filters An image processing system tiles an image data array. Each tile of image data is processed by applying a family of transform layers to the tile of image data so as to generate successive sets of transform coefficients. Each set of transform coefficients i... | 04/15/2003 |
| 6496608 | Image data interpolation system and method A pixel filling system or method begins with an initial set of image data that is a subset of data values in a data array fk,l representing data values at corresponding positions (k,l). Some of the fk,l values are initially undefined... | 12/17/2002 |
| 6411305 | Image magnification and selective image sharpening system and method An initial magnified image is generated using a lowpass magnification filter. The resulting image will generally have smaller image data gradients than the original image. Portions of the image that the user, or an application, want to sharpen are selecte... | 06/25/2002 |
| 6407747 | Computer screen image magnification system and method An image magnifying method and apparatus magnifies a portion of an image displayed on a computer display device.
