In this paper we presented a new approach to manipulate digital signal in order create features array, which can be used as signature retrieve the signal. Each is associated with local binary pattern (LBP) histogram; histogram will calculated based on LBP operator, then k-means clustering was generate required for each The proposed method implemented, tested and obtained experimental results we...

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...

In most previous works, histograms are simply treated as n-dimensional arrays or even reshaped into vectors when measuring the distances between them. However many histograms have their intrinsic topologies, such as HSV histogram (cone), shape context (polar), orientation histogram (circle). The topologies are important for so-called cross-bin distance, because they determine the similarities b...

This paper presents an efficient approach to rotation discriminative template matching. A hierarchical search divided in three steps is proposed. First, gradient magnitude is compared to rapidly localise points with high probability of match. This result is refined, in a second step, using orientation gradient histograms. A novel rotation discriminative descriptor is applied to estimate the ori...

In this paper we present a method for objects tracking in images sequence. This approach is achieved into two main steps. In the first one, we constructed the Local Binary Pattern (LBP) histogram pattern of each image in the sequence and the reference pattern. In the second one, we perform the algorithm by the pattern selected based on a distance measures to find similarity between two histogra...

Pigeons and humans chose which one of two alternative visual forms was identical to, or a mirror image of, a previously presented sample form. The two comparison forms were presented in various orientations with respect to the sample. The two species yielded similar accuracies, but although human reaction times depended linearly on the angular disparities, those of the pigeon did not. Humans ap...

The signing process is a critical step that organizations take to ensure the confidentiality of their data and safeguard it against unauthorized penetration or access. Within last decade, offline handwritten signature research has grown in popularity as common method for human authentication via biometric features. It not an easy task, despite importance this method; struggle such system stem f...

There are numerous stylish documents which do not have the traditional text layouts where printed text regions are not parallel to each other. Such complex layouts make text line extraction challenging due to multi-orientation of paragraphs. This paper introduces a system for the text line extraction from the complex layout documents. Proposed method is based on the concept of dilation and hist...
