Image fusion is a technique that integrate complimentary details from multiple input images such that the new image give more information and more suitable for the purpose of human visual perception. This paper presents a review on some of the image fusion techniques (simple average, simple minimum, simple maximum, PCA, DWT). Comparison of all the(More)
Image retrieval has been one of the most interesting and vivid research areas in the field of computer vision .Content-based image retrieval (CBIR) systems are used in order to automatically index, search, retrieve and browse image databases. Colour and texture features are important properties in content-based image retrieval systems. In this paper we have(More)
This paper aims at performing wavelet analysis on jpeg images using discrete wavelet transform for implementation in a still image compression system and to highlight the benefit of this transform relating to other techniques (DCT). The paper discusses important features of wavelet transform in compression of still images, including the extent to which the(More)
— Nighttime image context enhancement is one of the crucial areas in image processing as many objects can't be seen due to poor illumination of the video. The purpose of image or video enhancement is to improve the visual appearance of the video. In this paper, a new algorithm is proposed in which the illuminant area of the nighttime image is enhanced to(More)
