Digital Image Processing Laboratory : Image Halftoning

In this lab, we will cover a useful image processing technique called halftoning, which is the process of converting a gray scale image into a binary image. The process of halftoning is required in many present day electronic applications such as facsimile (FAX), electronic scanning and copying, and laser printing. This lab will cover the halftoning techniques known as ordered dithering and err...

Image Understanding at the GRASP Laboratory

Research in the GRASP Laboratory has two main themes, parameterized multi-dimensional segmentation and robust decision making under uncertainty. The multi-dimensional approach interweaves segmentation with representation. The data is explained as a best fit in view of parametric primitives. These primitives are based on physical and geometric properties of objects and are limited in number. We ...

Digital Image Processing Laboratory : The EM Algorithm

This laboratory explores the use of the expectation-maximization (EM) algorithm for the estimate of parameters. In particular, we will use the EM algorithm for two applications: clustering, and hidden Markov model training. You are encouraged to implement your solutions to this laboratory in Matlab. For an original derivation of the monotone convergence of the likelihood for the EM algorithm, t...
