| 发明名称 | System and method for removing image noise | ||
| 摘要 | A system and method for removing noise from images are disclosed herein. An exemplary system includes an edge-detection-based adaptive filter that identifies edge pixels and non-edge pixels in an image and selects a filtering technique for at least one non-edge pixel based on a comparison of the at least one non-edge pixel to a neighboring pixel region, wherein such comparison indicates whether the at least one non-edge pixel is a result of low-light noise. | ||

| 主权项 | 1. A system for removing noise from an image, the system comprising: an edge-detection-based adaptive filter configured to: identify edge pixels and non-edge pixels in the image,select a filtering technique for at least one non-edge pixel, out of a plurality of filtering techniques for non-edge pixels, based on whether a comparison of the at least one non-edge pixel to a neighboring pixel region indicates that the at least one non-edge pixel is a result of low-light noise, andgenerate a transformed image by applying the selected filtering technique to the image. | ||
