The purpose of this study is to design and develop an interactive dynamic simulation platform for digital image processing teaching. This platform is constructed and implemented by the hierarchical design. The user interfaces of platform are build by the graphical user interface controls of MATLAB and user operations are responded by writing callback functions. The abstract teaching contents and processing...
Resolution enhancement for stereo imaging aims to use a pair of stereo images to reconstruct another pair of images with higher resolution. To tackle this problem, a Bayesian resolution enhancement approach is proposed in this paper. Since the prior image model is essential for solving the ill-posed numerical issues encountered in the image resolution enhancement, the proposed approach exploits a...
This paper presents a novel blind super-resolution (SR) algorithm to enhance image resolution without the knowledge of the blurring functions. The primary motivation for developing the blind algorithm is due to the observation that most existing SR methods assume the blurs are known a priori, which may not be true in many real-world applications. In view of this, we formulate the SR problem into a...
The aim of multi-focus image fusion is to combine multiple images with different focuses for enhancing the perception of a scene. The critical issue in the design of multi-focus image fusion algorithms is to evaluate the local content information of the input images. Motivated by the observation that the marginal distribution of the wavelet coefficients is different for images with different focus...
The aim of image enhancement over distributed video sensor network (DVSN) is to fuse multiple images acquired by a set of video sensors to produce a single image with more visual information. For that, a wavelet-domain Bayesian approach is proposed in this paper. The proposed approach estimates the wavelet coefficients of the desired image by exploiting both the information provided by multiple images...
