Segmentation of blood vessels in retinal images provides early diagnosis of diseases like glaucoma, diabetic retinopathy and macular degeneration. Among these diseases occurrence of Glaucoma is most frequent and has serious ocular consequences that can even lead to blindness, if it is not detected early. The clinical criteria for the diagnosis of glaucoma(More)
At present most of the hospitals and diagnostic centers globally, use wireless media to exchange biomedical information for mutual availability of therapeutic case studies. The required level of security and authenticity for transmitting biomedical information through the internet is quite high. Level of security can be increased; authenticity of the(More)
The Electrocardiogram (ECG) is a sensitive diagnostic tool that is used to detect various cardio-vascular diseases by measuring and recording the electrical activity of the heart in exquisite detail. A wide range of heart condition is determined by thorough examination of the features of the ECG report. Automatic extraction of time plane features is(More)
Compression technique plays an important role indiagnosis, prognosis and analysis of ischemic heart diseases.It is also preferable for its fast data sending capability in the field of telemedicine.Various techniques have been proposed over years for compression. Among those Discrete Cosine Transformation(DCT), Discrete Wavelet Transformation(DWT), Fast(More)
This work proposes a DWT based Steganographic technique. Cover image is decomposed into four sub bands using DWT. Encoded Secret image using spiral scanning is hidden by alpha blending technique in HH sub bands. During embedding secret image is dispersed within HH band depending upon alpha value. Encoded secret images are extracted and decoded to recover(More)
Medical image processing covers a wide spectrum of activities growing vigorously in the last couple of decades. In this paper a method is proposed to detect ankle fractures with the help of wavelet analysis from the X-ray image of the fractured region. The wavelet analysis enables the availability of spectral information in low frequency region for short(More)
Blood cell smears contain huge amounts of information about the state of human health. This chapter proposes a Fuzzy c-means segmentation based method for the evaluation of blood cells of humans by counting the presence of Red Blood Cells (RBCs) and recognizing White Blood Cell (WBC) types using Harris corner detection. Until now hematologists gave major(More)
The essence of transmitting digital information in digital watermarking system and the dissymmetric digital watermarking framework lived on media content communication is being discussed in this paper. The protection and integrity of information during transmission is also discussed in this paper. Fast Fourier Transform (FFT) is applied for watermarking(More)
