We can measure the eye movement activity using eye tracking technology. Eye tracking gives us information about where do we look? What is ignored and how the pupil reacts to different stimuli. The eye tracking concept is basic but its process and interpretation can be very diverse and complex. ET measures the gaze points generated by our eye relative to the head. Eye trackers are availbble in either...
Nowadays, due to busy lifestyle of people, ignorance and tolerance of symptoms, slowly develops diabetes. It cause when body stops producing enough insulin which is essential to control the blood sugar. The amount of high sugar level affects vital organs of the body like kidney, heart, and brain. The diagnosis of diabetes typically confirmed on the basis of increased glucose level in the blood. Symptoms...
Plants are very important for human being as well as for other living species on the earth. The food that people eat daily, comes directly or indirectly from plants. In medical field, doctors use X-ray image to correctly identify disease. Here we used the same principle. Geometrical features and digital morphological features are extracted from 2-dimensional image of leaf. The aim of this study is...
Glaucoma is one of the eye disease. In glaucoma optic nerve head is damaged, due to intra ocular pressure is increased and if it is not cured earlier then it can cause permanent vision loss. This paper represents algorithm for detection of glaucoma using Optic Cup to Disc Ratio. For this work we have used 2D median filter and Multi threshold methods. On high resolution colored retinal funds images,...
Diabetes Mellitus (DM), commonly referred as diabetes is a disorder that most of the people suffer from and which also leads to death many of the times. Type 1, Type 2 and Gestational diabetes are the types of diabetes. The present study is of patients suffering from Type 1 DM. In Type 1 diabetes a patient has to take external insulin to maintain the blood glucose level (BGL). Insulin is a hormone...
WHO predicts that in year 2012 there are about 347 million people worldwide have diabetes, more than 80% of diabetes deaths occur in different countries. WHO projects that diabetes will be the 7th major cause leading death in 2030. Diabetic Retinopathy caused by leakage of blood or fluid from the retinal blood vessels and it will damage the retina. Non-proliferative diabetic retinopathy (NPDR) is...
HOCR is abbreviated as Handwritten Optical Character Recognition. HOCR recognizes handwritten characters from a digital image of documents. Shape identification and feature extraction is very important part of any OCR. Feature extraction defines shape of the character as precisely and as uniquely as possible. Zernike moments describes shape, identify rotation invariant due to its orthogonal property...
Glaucoma is an eye disease. In glaucoma retinal nerve fiber layers are damaged and if it is not treated earlier then it can cause permanent vision loss. This paper represents algorithm for detection of glaucoma using retinal nerve fiber layers. For this work we have used 2D median filter and HAAR wavelet transform methods. For this work we have also used Drishti-GS dataset which contains 101 glaucomatous...
Glaucoma is Eye dieses & one of the leading causes of blindness worldwide. It is due to the increase in intra ocular pressure within the eyes. The detection and diagnosis of glaucoma is very important. Here we present an algorithm which works on two different data base for the same purpose to calculate optic cup to disc ratio. For this purpose we use DRIONS-DB high resolution fundus images. From...
This research paper presents the leaf shape extraction for plant classification. Leaves are very important component of the plant which actually identifies and classify the plants. Classification of the plant by their leaf biometric features is commonly performed task of trained botanist and taxonomist. To perform this task they need to perform various set of operations. Because of this the task of...
Infertility is one of the major problems in human being. Sperm morphology is one of the evaluation techniques for male infertility. The aim of this paper is to perform sperm segmentation using image processing techniques and classification of sperm heads. The proposed system works on the digital images of sperm. The single Spermatozoa segmented into three parts Sperm Head, Sperm Mid Piece, and Sperm...
The varying writing style and critical representation of characters in Indian script makes Handwritten Optical Character (HOCR) challenging and has attracted researchers to contribute in this domain. ‘MODI’ Script had cursive type of writings in Devanagari, Marathi where large amount of historical documents were available and need to be digitally explored. The principal objective of this research...
Automatic Speech Recognition (ASR) by machine has attracted many researchers to design robust recognition system. Latest advances in speech recognition by incorporation of visual cues for enhancement of speech gives rise to Audio Visual Speech Recognition system. Multi-pose AVSR is gaining attention due to its robust feature extraction capability. This process is contributing in design of robust AVSR...
Identification and authentication is done using various biometric sign like fingerprints. The recognition rate of correct person is depending on quality of fingerprints images. Fingerprints quality also varying from rural and urban population. Rural population having more physical work than urban population. Therefore the ridges, valleys, bifurcation, joints, minutia etc. features are not good quality...
Biometric identifiers are the unique, measurable characteristics used to tag and describe individuals. Physiological characteristics are related to the shape of the body. Examples of biometric identifications are, fingerprint, face, DNA, Palm print, hand geometry, iris recognition, and retina. Human retina is another source of biometric system which provides the most reliable and stable means of authentication...
This paper proposes improved Template Matching algorithm that applied for the automatic extraction of text from image and video frames. Optical Character Recognition using Template Matching is a system model that is useful to recognize the character, alphabet & special character by comparing two images of the alphabet. The objectives of this system model are to develop a model for the Optical...
Audio visual speech recognition (AVSR) is a technique that uses image processing capabilities in lip reading to aid speech recognition systems in recognizing un-deterministic phones or giving preponderance among near probability decisions where as an lipreading is a technique of understanding speech by visually interpreting the movements of the lips, face and tongue with information provided by the...
Artificial Neural Network (ANN) are one of the recently explored advanced technologies which shows promise in the area of medical. In this paper, Radial Basis Function is used to predict the medical prescription of heart disease. This work includes the detailed information about the patient's symptoms and preprocessing was done. The trainee doctors can also use this web based tool for diagnosis and...
In this paper, we propose the comparison of original text in the form of bitmap image and extracted image by using various fonts of text as a bitmap image. The purpose of data hiding is to embed relating textural description into an image. The textural description and original host image can be extracted and reconstructed from the stego-image in the data extraction process. However, the reconstructed...
This recent technologies for recognizing fingerprints have proven as regards as reliable for security purposes. But, the efficient recognition is depending on the quality of fingerprint image and it is a complex computer problem while dealing with noisy and low quality images. The most common methods used to acquire the fingerprint images do not need expertise, but highly distorted images are still...
