9 Texture Analysis 9 Considerable knowledge and experience on Texture Analysis Developed several novel algorithms for Texture Analysis Segmentation of multi-textured images Textures which are even difficult to discriminate visually by human eye were being discriminated by the machine vision algorithm developed Features developed were affine transformation (scale, rotation, translation) invariant Document image (scanned documents) segmentation for separating textual and graphics parts applicable for second generation compression Features developed were invariant to skewness, resolution, rotation etc. Satellite image segmentation for classifying different regions like: habitation, vegetation, water bodies, man-made structures, open areas etc. Designed and developed a novel neuro-fuzzy based unsupervised classifier for this purpose

10 Texture Analysis 10 Input Textured image where some of the regions are not discriminable as different class even visually Segmented image based on different textured regions Novelty of the algorithm is that it identifies textured regions as different class which are even very difficult to identify visually by human Input Textured image where some of the regions are not discriminable as different class even visually Segmented image based on different textured regions Algorithm involves in-depth knowledge of Texture Analysis, Wavelet Analysis, Feature Extraction, Classification, Fuzzy Set Theory, Neural Network & Soft Computing

11 Document Segmentation – Second Generation Compression 11 Novel algorithm developed for segmentation of textual part from graphics part which is essential for second generation compression. Here text and graphics parts were considered as two different textured regions.

In the Calcutta IRS image the open space which is a race course and even the Howrah bridge were identified correctly.

13 Nodule (Lesion) Detection in Chest X- ray 13 4 US Patents Novel algorithms were developed for identification of nodules (lesions) in chest X-rays. Chest X-ray data is a 2D projection image where each pixel represents a volumetric integration posing a challenge in detection and estimation of nodules and their characteristics. Several algorithms were developed to reduce False Positives or Nodule-look-alikes detection. Algorithm involves in-depth knowledge of Segmentation, Mathematical modeling, Pre- & Post Processing, Fractal Analysis, Shape Analysis, Image Analysis, Machine Learning, Statistical Analysis

29 Bioacoustics 29 Bird Chirp Identification and Classification

30 Accelerometer Data Analysis 30 Golf Swing Key Points Identification

31 Watermark 31 Watermarking - novel algorithm developed to embed patient information in medical images as watermark The uniqueness and novelty of the algorithm lies in the fact that apart from the use of embedded watermark as an information source we can watermark some extra text information pertaining to the image. We see this as a revolutionary tool in the arsenal of a radiologist using a CAD suite, wherein he can embed certain crucial information into an image rather than relying on the DICOM header. The significant benefit would be the selective access of this information and its being free of traditional viewing platforms. Thus the watermark here acts in actual way of both conveying information as well as providing security. A failure of the watermark would mean the non-reliability of both the image as well as the additional information thereby maintaining its traditional purpose. Algorithm involves Wavelet Analysis, quantization, coding Published Patent

37 Identifying image tampering, alteration or forgery Image Forensic 37 Passive Authentication - P atterns of original images are distinguishable due to the different imaging devices and image processing inside them. Original patterns constrained by the statistical characteristics in natural scenes, physical conditions in a scene, etc. would be altered after tampering. Passive forensics can be converted to a problem of pattern recognition Solution to the problem is finding the different patterns according to the knowledge from various imaging devices or the manipulations or the natural scene constraints, etc. Selected patterns with distinguishing ability are crucial for this new technology

38 Passive Forensic 38 Identification of image source – Imaging devices have varying characteristics due to different physics apparatus image processing parameters applied inside the imaging devices – Lead to different patterns of the output images – Use these patterns as inherent fingerprints of the imaging devices to identify the source of the image Image X Imaging Device Knowledge of image acquisition model Compare Similarities between patterns and characteristic features measured. Confidence measure for each imaging device to identify the source of the image is computed.

39 Passive Forensic 39 Detection of image alteration – Original images always contain some consistent characteristics noise distribution light condition Characteristics change after image post-processing (alterations) Some features of the altered images become more or less inconsistent Finding the differences before and after the operations is the key of the technology Image X Original/ Altered Image Knowledge of image manipulation model Compare Extract features from image X and obtain the original/ altered patterns mainly using the knowledge of the image manipulation model. Compare the distance between the features and the patterns to decide whether or not image X has been altered

40 Image Forensic 40 Fourier analysis of histograms of the images to determine if a JPEG image underwent double compression Localize which portions underwent double compression by analyzing difference images Any forgery in the image or splicing of two images from different cameras can be identified by analyzing the correlations introduced by performing color filter array (CFA) interpolation and demosaicking Any tampering can be measured by the local correlation of camera noise or photo- response non-uniformity noise (PRNU) and the image Forgery due to splicing of images require resampling which disturbs the specific correlation of the image. Estimating this correlation using expectation maximization can identify the forgery A common manipulation is to copy and paste portions of an image to replicate an object or conceal a person in a scene called cloning. Presence of identical (or virtually identical) regions in an image can, therefore, be used as evidence of tampering. Image similarity measure, by matching key points in the images using different techniques like scale invariant feature transform (SIFT) and random sample consensus algorithm (RANSAC) can be used to identify this cloning

41 Image Forensic 41 Computer graphics (CG) capable of generating highly realistic images. But CG images are rendered under idealized models of geometry, lighting, camera optics and sensors, and their underlying statistics differ from those of photographic images. Image decomposition at different orientation, scale and spatial frequency that are localized in spatial position would capture all the statistical irregularities in case of CG images Creating a photo composite requires translation, scaling, rotations of portions of an image. Such image-based manipulations can change the effective intrinsic camera parameters. Differences in these estimated parameters can be used as evidence of tampering Shadow analysis (light travels in straight line so lines drawn on shadows and objects should intersect at one point (light source). This can be used to analyze any forgery Image created by splicing together individual images is difficult to exactly match the lighting effects due to directional lighting (e.g., the sun on a clear day). Differences in lighting can be a telltale sign of tampering. Direction of the light source can be estimated for different objects/people in an image, inconsistencies in the lighting direction can be used as evidence of tampering
