Abstract
Image defocus blur estimation techniques are described. In one or more implementations, fixed spatial frequencies that are usable to analyze an image for blur are selected. The selected spatial frequencies are input to a function used to determine frequency responses for pixels of the image. The frequency responses indicate a response of the pixels around a given pixel to the selected spatial frequencies. The spatial frequencies that are selected may be limited to spatial frequencies having a frequency magnitude from a set of discrete values. The discrete values may, for instance, range from a minimum frequency magnitude to a maximum frequency magnitude, and be spaced apart by a frequency magnitude increment. A number of frequencies that are selected at each magnitude may also be based on the frequency magnitude increment.
