Intensity inhomogeneity is a smooth intensity change inside originally homogeneous regions. The intensity inhomogeneity degrades performance of image processing algorithms. Intensity inhomogeneity correction methods are important image processing algorithms which are used to reduce the inhomogeneity. Brain image intensity inhomogeneity correction is one of the most important parts of clinical d...
Feature extraction by applying a threshold window to image intensity values is a simple and common image processing technique. We consider the case of 3D images where intensity based feature extraction is used to determine the volume of objects of interest. We show that the accuracy of volume determination is limited by partial volume (PV) effects. We outline a new method for correcting for PV ...
We employ quantum retrodiction to develop a robust Bayesian algorithm for reconstructing the intensity values of an image from sparse photocount data, while also accounting for detector noise in the form of dark counts. This method yields not only a reconstructed image but also provides the full probability distribution function for the intensity at each pixel. We use simulated as well as real ...
The browning kinetic was recorded using color data information from images of avocado slices. GLCM image texture was used to describe the reaction. In the experiment, images of avocado slices stored at 4°C were captured and saved in tiff format. The classical color intensity index (the mean L* value) and some statistics GLCM image textures were used. Results showed that it is possible to use GL...
