Pneumonia is a lung illness that affects the respiratory system. Both viruses and bacteria are capable of causing this condition. Affected individuals will have a more challenging time breathing and will likely experience some pain. If not treated immediately, it can be fatal. Hence, pneumonia needs to be detected as soon as possible. Patients with pneumonia typically exhibit fluid accumulation wi...Show More
Quantization Index Modulation (QIM) received tremendous attention in the field of information hiding and secure communication of multimedia data. The discloser of these set of algorithms by Chen and Wornell [1] in the year 1999 gave a new direction to watermarking and steganography research. This paper discusses various QIM realizations in 3D surface meshes. The approaches are divided into two cla...Show More
Remeshing is an important technique used for the improvement of the quality of 3D models. The original features of a particular mesh may distort or change while using certain remeshing techniques. This may impact further processing on the mesh as remeshing is considered as a pre-processing phase for most of the mesh processing operation. So to preserve the geometrical features or the actual unique...Show More
This paper describes an ANN based human facial expression recognition method. An automatic technique is generated for detecting 22 most important facial feature point and generation of facial feature vector by finding the Euclidian distances between some particular points. Here the key facial regions are found based on a defined face model. The face model is generated by the detection of the eyes ...Show More
Transmitted images may have many different applications like commercial, military and medical. To protect the information from unauthorized access secure image transfer is required and this can be achieved by image data encryption. But the encryption of whole image is time consuming. This paper proposed a partial encryption technique using DWT domain, pixel shuffling and modification of pixel valu...Show More
This paper describes a human face detection algorithm where human skin colour is detected using 2D Colour Space Skin Clustering Method in YCbCr color model. Then the face is detected using connected component analysis followed by a refining process containing a set of human face shape criteria.Show More
