Automatic face detection is a challenging task for computer vision and pattern recognition applications such as video surveillance and traffic monitoring. During the last few years, subspace methods have been proposed for visual learning and recognition which are sensitive to variations in illumination, pose and occlusion. To overcome these problems, the authors have proposed a method that combines block‐based tensor locality preservative projection (TLPP) with Adaboost algorithm which improves the accuracy of face detection. In the proposed algorithm Adaboost modular TLPPs (AMTLPPs), the face image is divided into overlapping small blocks and these block features are given to TLPP to extract the features where TLPP take data directly in the form of tensors as input. AMTLPP algorithm selects the optimal block features from the large set of the block features which forms the weak classifiers and are combined to form the strong classifier. A number of assessments are conducted for YouTube celebrity, McGill face dataset and also on collected video sequences of an own dataset recorded under indoor, outdoor, day, sunset and crowded environment. Experimental results show that the proposed approach is effective and efficient.

Abstract. The increase in availability of high performance, low-priced, portable digital imaging devices has created an opportunity for supplementing traditional scanning for document image acquisition. Cameras attached to cellular phones, wearable computers, and standalone image or video devices are highly mobile and easy to use; they can capture images making them much more versatile than desktop scanners. Should gain solutions to the analysis of documents captured with such devices become available, there will clearly be a demand in many domains. Images captured from images can suffer from low resolution, perspective distortion, and blur, as well as a complex layout and interaction of the content and background.In this paper, we propose an efficient text detection method based on Maximally Stable Exterme Region (MSER) detector, saying that how to detect regions containing text in an image. It is a common task performed on unstructured scenes, for example when capturing video from a moving vehicle for the purpose of alerting a driver about a road sign . Segmenting out the text from a clutterd scene greatly helps with additional tasks such as optical charater recognition (OCR). The efficiency of any service or product, especially those related to medical field depends upon its applicability. The applicability for any service or products can b achieved by applying thr basic principles of Software Engineering.
