Robust Noise Filtering in Image Sequences
Image sequences filtering have recently become a very important technical problem especially with the advent of new technology in multimedia and video systems applications. Often image sequences are corrupted by some amount of noise introduced by the image sensor and therefore inherently present in the imaging process. The main problem in the image sequences is how to deal with spatio-temporal ...
متن کاملAdaptive Noise Filtering of Image Sequences in Real Time
Filtering noise in image sequences is an important preprocessing task in many image processing applications, including but not limited to real-time x-ray image sequences obtained in angiography. The main objective in real-time noise filtering is to improve the quality of the resultant image sequences. Practically affordable approaches are generally suboptimal and deal with the spatial and tempo...
متن کاملGeological noise removal in geophysical magnetic survey to detect unexploded ordnance based on image filtering
This paper describes the application of three straightforward image-based filtering methods to remove the geological noise effect which masks unexploded ordnances (UXOs) magnetic signals in geophysical surveys. Three image filters comprising of mean, median and Wiener are used to enhance the location of probable UXOs when they are embedded in a dominant background geological noise. The study ar...
متن کاملRobust Guided Image Filtering
The process of using one image to guide the filtering process of another one is called Guided Image Filtering (GIF). The main challenge of GIF is the structure inconsistency between the guidance image and the target image. Besides, noise in the target image is also a challenging issue especially when it is heavy. In this paper, we propose a general framework for Robust Guided Image Filtering (R...
متن کاملHMM-Based Image Sequences Filtering
It is possible to divide image sequences into some states, where each state has same motion phase. By applying such operation before recognition processing, accuracy of the recognition will be improved. New image sequence ltering by using HMM is proposed in this paper, which can divide image sequences into multiple states. Performance of the ltering is improved by doing re-learning of the obser...
