doesn't have to make sense to you, but it's probably great for your health.
TweetThis post is a continuation from Biomedical Image Processing – IV. Contrast Stretching Contrast stretching (a.k.a. normalization) is very similar to histogram equalization, but it maps only a certain portion of the histogram to the full range. An example of this image enhancement technique is illustrated in Figure 17. If a and b are the [...]
TweetThis post is continuing from Biomedical Image Processing – III. Enjoy Basic Image Modification While image processing operations can be performed in hardware (e.g., in cases where speed is paramount), many image processing operations are performed in software. This section discusses some of the basic processing operations performed on different types of images, including image [...]
TweetContinuing from Biomedical Image Processing – I Image Properties Once an image is stored in digital format, it can be described by a number of different parameters. Some of the relevant parameters are briefly discussed here. The traditional convention for an image coordinate system is depicted in Figure 4. Figure 4. General convention for image [...]
TweetWhy do we study image processing? Images play a large role in the presentation of physiological information. Not all image data, however, are ideal. Images can be corrupted by noise, exhibit blur or spatial warping, contain non-optimal intensity/color representations, or simply be too large (or too small) to be of practical or diagnostic value. The [...]
