Mammogram—breast X-ray—is considered the most effective, low cost, and reliable method in early detection of breast cancer. Although general rules for the differentiation between benign and malignant breast lesions exist, only 15–30 % of masses referred for surgical biopsy are actually malignant. In this work, an approach is proposed to develop a(More)
The image mining technique deals with the extraction of implicit knowledge and image with data relationship or other patterns not explicitly stored in the images. It is an extension of data mining to image domain. The main objective of this paper is to apply image mining in the domain such as breast mammograms to classify and detect the cancerous tissue.(More)

In this paper we are proposing a technique for secret communication between Alice and Bob. We are using both cryptography and steganography. Firstly, we encrypt the secret message using our new cipher algorithm called twelve square substitution cipher algorithm, and then embed the cipher text in the carrier image in 6<sup>th</sup> and 7<sup>th</sup> bit(More)
In this paper the two sided, three sided and four sided side match steganography methods are proposed. In two sided side match method the two neighboring pixels such as upper and upper-right corner are exploited to take embedding decision. In three sided side match method the three neighboring pixels such as upper, upper-right corner and upper-left corner(More)

In this paper we present a technique for secure communication between two parties Alice and Bob. We use both cryptography and image steganography. We encrypt the secret message by using a new cipher which is extended from Hill cipher. Then the cipher text of the secret message is embedded into the carrier image in 6<sup>th</sup>, 7<sup>th</sup> and(More)
The purpose of this study was to develop a new method for automated mass detection in digital mammographic images using mass shape pattern. Masses were detected using a two steps process. First, the pixels in the mammogram images were scanned in 8 directions, and regions of interest (ROI) were identified using various thresholds. Then, a mass shape pattern(More)
