1. A method of determining edges of an image comprising: a. calculating a Gaussian wavelet coefficient of the image; b. retaining the Gaussian wavelet coefficient, wherein the Gaussian wavelet coefficient is above a first threshold; c. calculating a Haar wavelet coefficient of the image; d. retaining the Haar wavelet coefficient, wherein the Haar wavelet coefficient is co-positioned near a non-zero Gaussian wavelet coefficient; and e. calculating a color of an edge represented by the Gaussian wavelet coefficient and the Haar wavelet coefficient.
