Method and system for applying filter to image |
摘要 |
A computer-implemented method for applying a filter to an image comprising: receiving a filter setting, selecting a selected filter from a family of filters stored on a computer-readable storage medium, based at least on the filter setting, wherein the family of filters comprises a plurality of filters each being an approximation of a function on different orders, and applying the selected filter to a stored image with a processor. |

1. A computer-implemented method for applying a filter to an image comprising:
receiving a filter setting; selecting a selected filter from a family of filters stored on a computer-readable storage medium, based at least on the filter setting, wherein the family of filters comprises a plurality of filters each being an approximation of a function on different orders; determining parameters of the selected filter; and applying the selected filter to a stored image with a processor; wherein the family of filters comprise Gaussian blur filters and the filter setting comprises blur strength; wherein the Gaussian blur filter is an approximation of a Gaussian function represented byha(k)=∑i=0naiⅇ-λikσ; wherein σ is a standard deviation value based at least on the blur strength, i is a filter order, ai and λi are parameters; and wherein determining parameters of the Gaussian blur filter comprises calculating ai and λi by minimizing a mean square error function of ha(k). |
