A Novel Approach for Image Steganography in Spatial Domain
Published In: GJCST Part: F: Graphics & Vision Volume: 13 Issue: 7 This paper presents a new approach for hiding information in digital image in spatial domain. In this approach three bits of message is embedded in a pixel using Lucas number system but only one bit plane is allowed for alternation. The experimental results show that the proposed method has the larger capacity of embedding data, high peak signal to noise ratio compared to existing method...

Dynamic Hand Gesture Recognition of Arabic Sign Language using Hand Motion Trajectory Features
Published In: GJCST Part: F: Graphics & Vision Volume: 13 Issue: 5 In this paper we propose a system for dynamic hand gesture recognition of Arabic Sign Language. The proposed system takes the dynamic gesture (video stream) as input, extracts hand area and computes hand motion features, then uses these features to recognize the gesture. The system identifies the hand blob using YCbCr color space to detect skin color of hand.Thesystem classifies the inpu...

Mixed Pixel Resolution by Evolutionary Algorithm: A Survey
Published In: GJCST Part: F: Graphics & Vision Volume: 13 Issue: 5 Now a day’s Remote Sensing is a mature research area. Remote sensing is defined as a technique for acquiring the information about an object without making physical contact with that image via remote sensors. But the major problem of remotely sensed images is mixed pixel which always degrades the image quality. Mixed pixels are usually the biggest reason for degrading th...

Character Segmentation for Telugu Image Document using Multiple Histogram Projections
Published In: GJCST Part: F: Graphics & Vision Volume: 13 Issue: 5 TEXT line segmentation is one of the major component of document image analysis. Text line segmentation is necessary to detect all text regions in the document image. In this paper we propose an algorithm based on multiple histogram projections using morphological operators to extract features of the image. Horizontal projection is performed on the text image, and then line segments are ...

Digital Color Image Watermarking usingDWT-DCT Coefficients in RGB Planes
Published In: GJCST Part: F: Graphics & Vision Volume: 13 Issue: 5 Digital image watermarking is used to identify the authenticity and integrity and to show the identity of its owners. This paper presents a more secure method for copy right protection. In the proposed method, the color image is decomposed into 3 color channels Red, Green and Blue and then DWT and DCT are applied to B channel of the R, G and B channels. The colored Watermark image is dec...

Image Mosaicing with Invariant Features detection using SIFT
Published In: GJCST Part: F: Graphics & Vision Volume: 13 Issue: 5 There are situations where it is not possible to capture larger views with the given imaging media such as still cameras or video recording machines in a single stretch because of their inherent limitations. So to avoid such conditions a term Image Mosaicing comes into play. This Paper presents a complete system for mosaicing a group of still images with some amount of overlapping betwee...

Robust Automatic Face Recognition
Published In: GJCST Part: F: Graphics & Vision Volume: 13 Issue: 4 The crux of the character identification problem is to exploit the relations between videos and the associated texts in order to label the faces of characters with names. It has similarities to identifying faces in news videos. However, in news videos, candidate names for the faces are available from the simultaneously appearing captions or local transcripts. While in TV and movies, the ...
