  • Patent number: 9047673
    Abstract: A target extracting apparatus and method for extracting a target through probability modeling of pixel brightness values in an image, and a recording medium storing a program for performing the method, are disclosed. The method includes extracting a background image from an input image, modeling brightness values of the input image and the background image based on a Gaussian distribution to generate an input image modeling result and a background image modeling result, calculating likelihood ratios for determining whether a pixel in the input image corresponds to a target based on a correlation between the input image modeling result and the background image modeling result and target templates having different sizes; determining a location of the target based on the calculated likelihood ratios; and outputting the determined location of the target.

  • Publication number: 20150015727
    Abstract: Provided are an apparatus and method for outputting a stabilized image even when a camera sways. The method includes: applying a first compensated motion to the image to acquire a first stabilized image, wherein an accumulation result of first motions, each of which is estimated between adjacent images from a reference image to an arbitrary image, is inversely transformed into the first compensated motion; and acquiring a second motion estimated between the reference image and the first stabilized image and applying the accumulation result of the first motions and a second compensated motion to the image to acquire a second stabilized image. An accumulation result of the second motion is inversely transformed into the second compensated motion.
