Image quality assessment means estimating the quality of an image and it is used for many image processing applications. Image quality can be measured in two ways, subjective and objective method. Objective method is more preferable than subjective because most of the time the original image is not available for the comparison and it is not that much expensive like the subjective method. These ...

Image processing algorithms related to remote sensing have been tested and utilized on the Hadoop MapReduce parallel platform by using an experimental 112core high-performance cloud computing system that is situated in the Environmental Studies Center at the University of Qatar. Although there has been considerable research utilizing the Hadoop platform for image processing rather than for its ...

We present a low frequency watermarking method adaptive to image content. The image content is analyzed and properties of HVS are exploited to generate a visual mask of the same size as the approximation image. Using this mask we embed the watermark in the approximation image without degrading the image quality. Watermark detection is performed without using the original image. Experimental res...

The main aim is Image Enhancement of BioMedical MRI Images Using Morphology technique. There are basically four operations in Morphology technique: Dilation, Erosion, Opening an Image and closing an Image. Basically I am going to use Dilation and erosion operations of the Morphology Technique for Image Enhancement. Previously I used Histogram Technique for enhancing image clarity; I collected V...

Image retrieval is an important research field which has received great attention in the last decades. In this paper, we present an approach for the image retrieval based on the combination of text-based and content-based features. For text-based features, keywords and for content-based features, color and texture features have been used. Query in this system contains some keywords and an input...

The principle of image enhancement is to improve the interpretability of information contained in the image for human perception or to provide a more suitable input for automated image processing systems. Many images like medical images, satellite images, aerial images and natural images suffer from contrast and noise issues. It is necessary to enhance the contrast and remove the noise to incre...

Fuzzy image processing is a powerful tool formulation of expert knowledge edge and the combination of imprecise information from different sources. The fuzzy technique is an operator in order to simulate at a mathematical level the compensatory behavior in process of decision making or subjective evaluation. Edge is a basic feature of image. The image edges include rich information that is very...

-In the today’s high scale communication of data there is a pressing need is generated for protection of the data information from many of the illegal duplication and modifications. For this purpose image watermarking is getting a very growing focus for a solution to the theft and tampering by involving the applications of advanced digital image processing operations to watermark copyright and ...
