In this paper, a smart home security system by using local binary pattern histograms (LBPH) face detection algorithm is proposed to enhance the security level of entry-system. Face recognition is an interesting but challenging in machinelearning field and impacts important applications in many areas such as remote sensing, machine/robot vision, patternrecognition, medical field, banking and security system access, and authentication in personal electronics gadget. In this research paper, we proposed the door lock security system using imageprocessing instead of traditional key and digital lock system. The imageprocessing mainly consists of three parts, namely face representation, feature extraction and identification of face. Face representation represents how to model a face with LBPH algorithms of detection and recognition. The most useful and unique features of the face image are extracted in the feature extraction phase. In the identification of face the new face image is compared with the images which are already extracted and saved on database. Face detection and recognition method was applied to allow the authorized dwellers and the guest and prevent unwanted person to enter inside the house.

In this paper we propose an evidencial measure for Multiwavelet best basis selection. The main idea is like Wavelet Packet, WP with the best basis selection where the filter applied to the signal varies adaptically with time. Here instead of entropy, we use the plausibility state(the degree of beliefs in the merit) in the image, because we can gain other measure that is more sophisticated. Finally we approve the efficiency of using Multiwavelets with adaptive tree structure with aoolying to imageprocessing.

When implemented in hardware, image-processing algorithms should be robust to memory limitations because some hardware architectures may not have memory size as large as the whole frame size. Although this is not generally a problem for low-level processing, higher-level understanding, such as object detection, demands novel solutions because the available information may, in some cases, be very local, e.g., only a partial view of the object could fit in the available memory size. In this paper, we propose a novel hardware-oriented overlaid text detection algorithm that can detect text with height as large as five times the memory size. The algorithm integrates a connected component (CC)-based algorithm with a texture-based machinelearning approach. The CC-based algorithm uses character-level features in the horizontal direction whereas the texture-based algorithm extracts block-based features to integrate information from all directions. Furthermore, the texture-based algorithm employs a support vector machine (SVM) to benefit from the strength of machinelearning tools. In order to detect text of large font size, we also propose a novel hardware-oriented, height-preserving multi-resolution analysis. Finally, the results of the two classifiers as well as color and edge cues are used for the final pixel-based text/non-text decision.

image fusion is an important tool for remote sensing data processing technology, as many Earth observation satellites provide both high-resolution panchromatic and low-resolution multispectral images. This paper presents a new image fusion method that combines IHS transform and curvelet transform. Experiments carried out on a Enhanced Thematic Mapper Plus image show that the proposed method quantitatively outperforms state-of-the art image fusion methods, in terms of geometric, radiometric, and spectral fidelity.

This paper proposes a method to establish joint ownership of digital images by embedding imperceptible digital pattern in the image. This digital pattern is generated from biometric features of more than one subject in a strategic matter so that the identification of individual subject can be done and the multiple ownership of the digital images can be established. This digital pattern was embedded and extracted from the image and the experiments were also carried out when the image was subjected to signal processing attacks. Coefficients of mid frequency band discrete cosine transform was used for embedding as these coefficients do not adversely affect the perceptual transparency and is also significantly robust to normal signal processing attacks. Experimental results indicate that the insertion of this digital pattern does not change the perceptual properties of the image and the pattern survives signal processing attacks which can be extracted for unique identification.

In this paper, a structural representation and fuzzy matching scheme is proposed for off-line multi-font Chinese character recognition. Firstly, a Chinese character is decomposed into eight stroke types. Secondly, a complete structural attribute feature codes among different type of strokes are defined and extracted. Lastly, a fuzzy matching scheme and dynamic programming algorithm is used for detailed match between an input character and candidate characters. Experiment on about 5140 daily used characters shows that our method can achieve 96.23% recognition accuracy.
