Preserving Median Filtering Algorithm in Chip Images
نویسنده
چکیده
The types and characteristics of noise in chip images were analyzed in this paper. A new kind of details preserving adaptive median filtering algorithm with directional sub-window was introduced in which the shape and size of filtering window can be adjusted according to the noise level and the sensitivity can be set by parameter. The filter can effectively get rid of most of the impulse noise and speckles from the chip image, and improve the accuracy of processing and analyzing image.

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 کاملAn Enhanced Median Filter for Removing Noise from MR Images
In this paper, a novel decision based median (DBM) filter for enhancing MR images has been proposed. The method is based on eliminating impulse noise from MR images. A median-based method to remove impulse noise from digital MR images has been developed. Each pixel is leveled from black to white like gray-level. The method is adjusted in order to decide whether the median operation can be appli...

متن کاملNew Filtering Technique for the Impulsive Noise Reduction in Color Images
We present a novel approach to the problem of impulsive noise reduction for color images. The new image-filtering technique is based on the maximization of the similarities between pixels in the filtering window. The method is able to remove the noise component, while adapting itself to the local image structure. In this way, the proposed algorithm eliminates impulsive noise while preserving ed...

Methods for face recognition which are based on face structure are among techniques without supervision and produce unfavorable results in the presence of linear changes in images. PCA is a linear transform and a powerful tool for data analysis but does not produce good results for face recognition when there are non-linear changes resulting from changes in position, intensity and gesture in th...
