Histo and Interval type of Data Space Every sample is multi-featured , and the generic understanding that every feature is characterized by an unique numeric value is an ideal expectation.The pragmatic aspects that every feature could be composed of several observations,could be due to temporal assimilation,could be descriptive;and that even a sample itself need not be an individual but could be a 'collective unit' , would make the data representation , complex from algorithmic perspective,though philosophically that is the most natural or in other words the most generic. "Edwin Diday" phrases such generic data analysis as 'Symbolic Data Analysis-SDA'. From Big-Data perspective clustering/classification analysis of such Symbolic samples requires an effective way to compute Distance between such samples. A simpler way of visualizing such Symbolic features is to represent them as histograms and a generic way to compute distances between Histo-Symbolic Objects will be presented. Further, if time permits, a model for dimensionality reduction of interval type of Symbolic features will also be presented.

Digital Satellite Image Processing and Applications in Natural Resource Management With the advent of new and advanced satellite sensors, having better spatial and spectral capabilities, the satellite image processing has become an important tool for various types of studies including natural resource management. In this talk, the retrieval of critical soil-landscape parameters using multi-sensor data by the application of non-parametric predictive approach will be discussed. Mapping the spatial distribution of soil-landscape parameters is important for implementing soil use and management decisions. The key parameters, below surface, at surface and above surface are dynamic under a range of soil and climatic conditions. There is clear need for more efficient mapping, understanding and management of ‘soil’. This is especially true in light of the rapid urbanisation worldwide, which require continuous monitoring of resource consumption. However, the quantitative modelling for prediction can be one approach, but, understanding complex and interconnected linkages between soil-landscape parameters under a range of soil and climatic conditions are key open question for scientific community.

Multi-view 3D Reconstruction This talk would be about reconstruction of rigid 3D scenes captured by multiple cameras or the same camera from multiple locations. The basics of formation of images and the underlying camera model and coordinate systems would be explained. In the problem, both the 3D camera geometry and the correspondences in the images captured are unknown. The camera geometry and the correspondences are recovered simultaneously and these estimates are used to finally generate a refined 3D model.
Wide Baseline Image Matching This part of the talk would focus on the problem of estimation of correspondences and camera geometry when the images have undergone high transformation and/or occlusion among other reasons leading to lower intersection of the images in 3D space.

Cross-Language Framework for Low-Resource Handwritten Image Analysis Handwritten image analysis has long been an active research area because of its complexity and challenges due to a variety of handwritten styles. Dataset is a necessary and important resource to develop any recognition/word-spotting system for benchmarking. It has been observed that the availability of training data is not uniformly distributed for all scripts. Hence, analysis of low-resource handwritten scripts is difficult as sufficient training data is not available and it is often expensive for collecting data of such scripts. In this talk, a cross language framework will be presented. The framework exploits a large resource of dataset for training and uses it for analyzing data of low-resource scripts.

This talk would focus on introducing the basic architecture of biometric recognition systems and their associated application domains. We would also discuss about some of the challenges associated with designing such systems including their security issues.
