Filtering image email spam is considered to be a challenging problem because spammers keep modifying the images being used in their campaigns by employing different obfuscation techniques. Therefore, preventing text recognition using Optical Character Recognition (OCR) tools and imposing additional challenges in filtering such type of spam. In this paper, we propose an image spam filtering tech...

Evaluation have been done to different enhancement techniques applied to ultrasound kidney images to see which enhancement techniques is the most suitable techniques that can be applied to the kidney images before segmenting the edge of the kidney. Five common enhancement techniques have been used including the spatial domain filtering, frequency domain filtering, histogram processing, morpholo...

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...

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 i...

One of the more rapidly growing areas in search technology is image search. With this availability comes the natural need to filter offensive content, to prevent Pornography images from reaching the wrong eyes. Filtering and blocking software is one of the most frequently touted prevention devices. As any user of these services is aware, they often fail to remove offensive images. The reasons a...

Purpose. The purpose of this article is to develop a preprocessing method for digital multispectral remote sensing images obtained through optical and infrared means in the electromagnetic spectrum. aims ensure invariance with respect positional formation conditions that determine spatial radiometric resolution. By implementing homomorphic filtering method, we can significantly increase informa...
