Fast Implementations of Temporal Color Image Filtering
نویسندگان
چکیده
The quality of the displayed image during minimal-invasive operations (endoscopy) may be low due to highlights and water vapor in front of the camera lens. In some cases, image processing like temporal color vector median filtering may enhance the visual quality of the images [8]. In this contribution we present a new technique of ordering, filtering and re-ordering of color image pixels that implements temporal filtering by using fast implementations of spatial filters. As an example for a fast spatial filtering library, we use the Intel Image Processing Library (IPL). A temporal color median filter was implemented with the new technique. Computing time and image enhancement were evaluated for this filter.

A PRACTICAL APPROACH TO REAL-TIME DYNAMIC BACKGROUND GENERATION BASED ON A TEMPORAL MEDIAN FILTER
In many computer vision applications, segmenting and extraction of moving objects in video sequences is an essential task. Background subtraction, by which each input image is subtracted from the reference image, has often been used for this purpose. In this paper, we offer a novel background-subtraction technique for real-time dynamic background generation using color images that are taken fro...
متن کاملSuper-Resolution Image Reconstruction Using Non-Linear Filtering Techniques
Super-resolution (SR) reconstruction is a filtering technique that aims to combine a sequence of under-sampled and degraded low-resolution images to produce an image at a higher resolution. The reconstruction attempts to take advantage of the additional spatio-temporal data available in the sequence of images portraying the same scene. The fundamental problem addressed in super-resolution is a ...
متن کاملContour and Detail Detection for Spatially Adaptive Color Median Filtering
In this paper, we present a spatially adaptive filter for color median filtering. Several alternative implementations of such a filter are given, using different ways of gradient computation. Then, several methods of color median filtering are compared in terms of performance on a particular image. Vector median filters are considered as well as median filters inspired by grey-

̳View plus depth‘ is a 3D video representation where a single color video channel is augmented with per-pixel depth information in the form of gray-scale video sequence. This representation is a good candidate for 3D video delivery applications, as it is display agnostic and allows for some parallax adjustments. However, the quality of the associated depth is an issue, as the depth channel is us...
متن کاملParameterless Discrete Regularization on Graphs for Color Image Filtering
A discrete regularization framework on graphs is proposed and studied for color image filtering purposes when images are represented by grid graphs. Image filtering is considered as a variational problem which consists in minimizing an appropriate energy function. In this paper, we propose a general discrete regularization framework defined on weighted graphs which can be seen as a discrete ana...
