    摘要: Example embodiments disclosed herein relate to image stabilization. Image stabilization includes techniques used to reduce jitter associated with the motion of a camera. Image stabilization can compensate for pan and tilt (angular movement, equivalent to yaw and pitch) of a camera or other imaging device. Image stabilization can be used in still and video cameras, including those found in mobile devices such as cell phones and personal digital assistants (PDAs).

    摘要: Systems, methods, and machine-readable and executable instructions are provided for filtering image data. Filtering image data can include determining a desired depth of field of an image, determining a distance between a pixel of the image and the desired depth of field. Filtering image data can also include adjusting a contrast of the pixel in proportion to a magnitude of a weight of the pixel, wherein the weight is based on the distance.

    摘要: Methods and apparatuses for determining a skew angle of text relative to an axis are disclosed herein. One exemplary embodiment of the method comprises locating a first portion of the text that has a spatial frequency greater than a first preselected value. The method continues with locating a second portion of the text that has a spatial frequency greater than a second preselected value. A line is fitted between the first portion of the text and the second portion of the text. The angle between the line and the axis is measured, wherein the angle corresponding to the skew angle.
