The most challenging issues in video forensic is about detecting tampered moving objects from video sequences. Approaches based on moving object are more complex because making a distinction between tampered and non-tampered regions is difficult. Hence, this study proposed block matching algorithm (BMA) in video copy-move forgery detection scheme to detect regions that represent either tampered or...
Since 2003, the scan line corrector (SLC) of the Landsat 7 Enhanced Thematic Mapper Plus (ETM+) sensor has failed permanently, inhibiting the retrieval or scanning of 22% of the pixels in each Landsat 7 SLC-off image. This utter failure has seriously limited the scientific applications and usability of ETM+ data. Precise and complete recovery of the missing pixels for the Landsat 7 SLC-off images...
This paper presents the issues and challenges faced for steganographic techniques that uses MP3 (Moving Picture Experts Group-1 "MPEG-1" Audio Layer 3) files as the cover or carrier file. The problem of steganographic techniques for MP3 is variety of MP3 states, where it exists at higher or lower bit rates, with higher or lower resulting quality. These have profound effects on strength of...
In this paper, an illumination normalization technique for edge-based face recognition on face images with non-uniform illumination conditions, is proposed. The proposed illumination normalization technique fuses the merits of color (Red, Green and Blue) normalization (Nrgb) and gamma correction (GC) for color images. By the fusion of these methods the image becomes independent of the change in face...
In domain of analytic cursive word recognition, there are two main approaches: explicit segmentation based and implicit segmentation based. However, both approaches have their own shortcomings. To overcome individual weaknesses, this paper presents a hybrid strategy for recognition of strings of characters (words or numerals). In a two stage dynamic programming based, lexicon driven approach, first...
This paper presents two new preprocessing techniques for cursive script recognition. Enhanced algorithms for core-region detection and effective uniform slant angle estimation are proposed. Reference lines composed of core-region are usually obtained as the ones surrounding highest density peaks, but are strongly affected by the presence of long horizontal strokes and erratic characters in the word...
