— Feature selection refers to the problem of selecting relevant features which produce the most predictive outcome. In particular, feature selection task is involved in datasets containing huge number of features. Rough set theory has been one of the most successful methods used for feature selection. However, this method is still not able to find optimal(More)
Transformation model plays a vital role in medical image processing. This paper describes a new Transformation model (NTM) which is hybrid of linear and non linear Transformations techniques for the detection of tumor. In NTM, patient image is compared with reference images, which is block based. An image similarity measure quantifies the degree of(More)
In Medical Field telemedicine and tele diagnosis is gaining momentum at a faster rate. So security and authentication for medical images are very important. This paper describes a new solution to digital watermarking of medical images. It uses Independent Component Analysis (ICA) to project the image into a basis with its components as satistically(More)
Rapid and innovative improvement in wireless communication technologies has led to an increase in the demand for mobile internet transactions. However, internet access from mobile devices is very expensive due to limited bandwidth available on wireless links and high mobility rate of mobile hosts. When a user executes a transaction with a web portal from a(More)
This study presents design and implementation of an efficient skeletal bone age assessment (BAA) procedure based on features extracted from two dominant wrist bone structures (radius & carpal bones). System works according to renowned Tanner & Whitehouse (TW2) method, based on carpal and epiphyseal region of interest (ROI). It ensures accurate and robust(More)
Maps are used to describe far-off places. It is an aid for navigation and military strategies. Mapping of the lands are important and the mapping work is based on (i). Natural resource management & development (ii). Information technology ,(iii). Environmental development ,(iv). Facility management and (v). e-governance. The Landuse / Landcover system(More)
The work explains an efficient method for skeletal bone age assessment (BAA) from the epiphysis/metaphysis of phalanges using Hausdorff distance as the measure for classification. The method was based on the Tanner and Whitehouse (TW2) method of BAA. The system guaranteed accurate BAA for the age range 0-10 years for both male and female. The input image(More)
This paper presents the comparative study on four computerized skeletal Bone Age Assessment (BAA) methods using the partitioning technique. The four systems studied work according to the renowned Tanner and Whitehouse (TW2) method, based on the Region of Interest (ROI) taken from the wrist bones. The systems ensure accurate and robust BAA for the age range(More)
