Removal of noise uses various natural image priors, including gradient based, sparse representationbased and nonlocal self similarity-based ones. The existing denoising algorithm tends to smooth the fine scale image textures, when removing noise, it degrades the image visual quality. To address this problem, a texture enhanced image denoising method is introduced. As a result, the gradient hist...

The traffic sign recognition system is a vital aspect of an intelligent transportation since it provides information to drivers help them drive more safely and effectively. This paper addresses some these concerns, which will be accomplished in two steps. first the detection signs, divided into stages. After picture has been preprocessed emphasize relevant information, signs are segmented based...

In this paper, we present a new and effective image indexing technique that employs local uni-color and bi-color distributions and local directional distribution of intensity gradient. The image is divided into 4 by 4 non-overlapping blocks. Each block, based on its gradient magnitude, is classified as uniform or non-uniform. Using the average of each color component for the pixels of a uniform...

Remote sensing is a field that has wide use, leading to the fact that it has a great importance. Therefore performance of selected features plays a great role. In order to gain some perspective on useful textural features, we have brought together state-of-art textural features in recent literature, yet to be applied in remote sensing field, as well as presenting a comparison with traditional o...

We address the problem of finding deformation between two images for the purpose of recognizing objects. The challenge is that discriminative features are often transformation-variant (e.g. histogram of oriented gradients, texture), while transformation-invariant features (e.g. intensity, color) are often not discriminative. We introduce the concept of attribute flow which explicitly models how...

Aksara Sasak adalah warisan budaya Lombok yang sangat penting untuk dilestarikan agar tidak punah diterpa perkembangan zaman. Paper ini mengusulkan perancangan model klasifikasi tulisan tangan karakter aksara menggunakan metode Histogram of Oriented Gradient (HOG) dan Multinomial Logistic Regression (MLR). Metode HOG digunakan melakukan ekstraksi fitur pada citra Sasak. dapat mendeskripsikan be...

Most multi-camera systems assume a well structured environment to detect and match objects across cameras. Cameras need to be fixed and calibrated. In this work, a novel system is presented to detect and match any objects in a network of uncalibrated fixed and mobile cameras. A master-slave system is presented. Objects are detected with the mobile cameras (the slaves) given only their observati...

Copy-Move is one of the most common technique for digital image tampering or forgery. Copy-Move in an image might be done to duplicate something or to hide an undesirable region. In some cases where these images are used for important purposes such as evidence in court of law, it is important to verify their authenticity. In this paper the authors propose a novel method to detect single region ...
