• Standard test image Wikipedia

    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.

    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 Söderberg, 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.

    Color Composite Images. A color composite image is similar to the color images one would find in the image processing software Photoshop. In Photoshop these images are made of "layers", and in Fiji they are made of "channels". Both "layers" and "channels" are the same idea. The advantages of using this type of image instead of RGB images include:
