In this article, a new fragile, blind, high payload capacity, ROI (Region of Interest) preserving Medical image watermarking<br />

(MIW) technique in the spatial domain for gray scale medical images is proposed. We present a watermarking scheme<br />

that combines lossless data compression and encryption technique in application to medical images. The effectiveness of<br />

the proposed scheme, proven through experiments on various medical images through various image quality measure matrices<br />

such as PSNR, MSE and MSSIM enables us to argue that, the method will help to maintain Electronic Patient Report(EPR)/DICOM<br />

data privacy and medical image integrity.<br />

There is a large number of possible facial attributes such as hairstyle, with/without glasses, with/without mustache, etc.<br />

Considering large number of facial attributes and their combinations, it is difficult to build attributes classifiers for all possible<br />

combinations needed in various applications, especially at the designing stage. To tackle this important and challenging<br />

problem, we propose a novel efficient facial attributes recognition algorithm using a learned spatial code<strong>book</strong>.<br />

The Maximum Entropy and Maximum Orthogonality (MEMO) criterion is followed to learn the spatial code<strong>book</strong>. With<br />

a spatial code<strong>book</strong> constructed at the designing stage, attribute classifiers can be trained on demand with a small number<br />

of exemplars with high accuracy on the testing data. Meanwhile, up to 600 times speedup is achieved in the on-demand<br />

training process, compared to current state-of-the-art method. The effectiveness of the proposed method is supported by<br />

convincing experimental results.<br />

Feature Space Hausdorff Distance for Face Recognition<br />

We propose a novel face image similarity measure based on Hausdorff distance (HD). In contrast to conventional HDbased<br />

measures, which are generally applied in the image space (such as edge maps or gradient images), the proposed<br />

HD-based similarity measure is applied in the feature space. By extending the concept of HD using a variable radius and<br />

reference set, we can generate a neighbourhood set for HD measures in feature space and then apply this concept for classification.<br />

Experiments on the Labeled Faces in the Wild; and FRGC datasets show that the proposed measure improves<br />

the overall classification performance quite dramatically, especially under the highly desirable low false acceptance rate<br />

conditions.<br />

How to Measure Biometric Information?<br />

Being able to measure the actual information content of biometrics is very important but also a challenging problem. Main<br />

difficulty here is not only related to the selected feature representation of the biometric data, but also related to the matching<br />

algorithm employed in biometric systems. In this paper, we propose a new measure for measuring biometric information<br />

using relative entropy between intra-user and inter-user distance distributions. As an example, we evaluated the proposed<br />

measure on a face image dataset.<br />
