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 [...]

TweetWhy is temperature measurement important? When you are calibrating equipment, you will probably want to account for temperatures associated with the system. Here is some information about temperature measurement that might help you better understand. Types of temperature measurements The majority of physical processes are affected, to one degree or another, by temperature. Whether these [...]
