This paper describes an indexing system for use in Content Based Image Retrieval. The standard colour histogram approach is simple, eÆcient, and robust. However, it does not include shape information, which leads to problems (e.g. many-to-many mappings). To remedy this we use additional features in an attempt to incorporate shape and textual information to the index key. Our experiments showed ...

In this paper, we present local image descriptor using VQ-SIFT for more effective and efficient image retrieval. Instead of SIFT's weighted orientation histograms, we apply vector quantization (VQ) histogram as an alternate representation for SIFT features. Experimental results show that SIFT features using VQ-based local descriptors can achieve better image retrieval accuracy than the conventi...

A calibration pattern detection method is proposed wherein a bimodal distribution is approximated for the intensity histogram of the calibration pattern. Because the histogram of the calibration pattern, such as black and white squares, is assumed to be bimodal, pattern detection is employed to determine the best threshold separating the two modes of the histogram. As most real images may inclu...

Multimedia analysis benefits from understanding the emotional content of a scene in a variety of tasks such as video genre classification and content-based image retrieval. Recently, there has been an increasing interest in applying human bio-signals, particularly eye movements, to recognize the emotional gist of a scene such as its valence. In order to determine the emotional category of image...

Inspired by Weber's Law, this paper proposes a simple, yet very powerful and robust local descriptor, Weber Local Descriptor (WLD). It is based on the fact that human perception of a pattern depends on not only the change of a stimulus (such as sound, lighting, et al.) but also the original intensity of the stimulus. Specifically, WLD consists of two components: its differential excitation and ...

In most of the video analysis applications, object detection and tracking play vital role. Most algorithms fail to predict multiple objects with varying orientation. this paper, goal is identify track using different feature extraction methods like Locality Sensitive Histogram, Histogram Oriented Gradients Edges. These features are subjected train classifier that can detect orientations. Experi...
