    OverviewHistorical originsCommon test imagesSee alsoExternal links

    A standard test image is a digital image file used across different institutions to test image processing and image compression algorithms. By using the same standard test images, different labs are able to compare results, both visually and quantitatively. The images are in many cases chosen to represent natural or typical images that a class of processing techniques would need to deal with. Other test images are chosen because they present a range of cha

  • Lenna - Wikipedia

    Lenna or Lena is the name given to a standard test image widely used in the field of image processing since 1973. It is a picture of the Swedish model Lena Forsén, shot by photographer Dwight Hooker, cropped from the centerfold of the November 1972 issue of Playboy magazine. The spelling "Lenna" came from the model's desire to encourage the proper pronunciation of her name.

  • 1. Introduction to image processing Digital Image

    Image processing is a method to perform some operations on an image, in order to get an enhanced image or to extract some useful information from it. It is a type of signal processing in which input is an image and output may be image or characteristics/features associated with that image. Nowadays, image processing is among rapidly growing technologies.

  • Local standard deviation of image - MATLAB stdfilt

    J = stdfilt(I) performs standard deviation filtering of image I and returns the filtered image J.The value of each output pixel is the standard deviation of the 3-by-3 neighborhood around the corresponding input pixel. For pixels on the borders of I, stdfilt uses symmetric padding. In symmetric padding, the values of padding pixels are a mirror reflection of the border pixels in I.
