Abstract
Various embodiments of edge detection systems and methods are disclosed. One method embodiment, among others, comprises receiving an image (602), applying a box-spline based tight wavelet frame to the image to decompose the image into low pass and high pass portions (604), and reconstructing the image from the high pass portions to yield edges of the image (606).
Claims22
An image edge detection system (550), comprising:
- memory (514) with image edge detection software (500);
- a processor (512) configured with the image edge detection software to receive an image (100), apply a box-spline based tight wavelet frame to the image to decompose the image into low pass and high pass portions, and reconstruct the image from the high pass portions to yield edges of the image.
An image edge detection method (500a), comprising:
- receiving an image (602);
- applying a box-spline based tight wavelet frame to the image to decompose the image into low pass and high pass portions (604);
- and
- reconstructing the image from the high pass portions to yield edges of the image (606).
