Fingerprint friction ridge features are generally described in a hierarchical order at three different levels, namely, Level 1 (ridge flow), Level 2 (minutiae points) and Level 3 (pores and ridge shape, etc.). Current Automated Fingerprint Identification Systems (AFIS) generally rely only on a subset of Level 1 and Level 2 features (minutiae and core/delta) for matching. On the other hand, late...

In this paper we tackle the problem of automatically aligning an unordered set of range views. We propose a full pipeline that goes from the scans to the complete 3D model. The emphasis is on the automation – no manual intervention is require – and on the fact that no knowledge on the acquisition sequence is assumed. The contribution is twofold: in the pre-alignment phase a voting scheme is pro...

A smart and simple algorithm is presented in this paper for vehicle’s license plate recognition system. Based on pattern matching, this algorithm can be applied for real time detection of license plates for collecting data for surveying or for some application specific purposes. The proposed system has been prototyped using C++ and the experimental results have been shown for recognition of Alb...

Automatic Number Plate Recognition (ANPR) plays an important role in Intelligent Transport System. Number plate extraction is the major key step before the plate recognition. This paper presents a method for extraction and recognition of the vehicle number plate from the image automatically. The camera is used to capture the image automatically. The segmentation is used to segment the character...

A strategy of automatic answer retrieval for repeated or similar questions in user-interactive systems by employing semantic question patterns is proposed in this paper. The used semantic question pattern is a generalized representation of a group of questions with both similar structure and relevant semantics. Specifically, it consists of semantic annotations (or constraints) for the variable ...

This paper addresses the problem of retrieval from graph databases. Graph databases store graph structures instead of tables. Typically, graph databases are applicable in domains that require storage and retrieval of structural information. One of the main issues in graph databases is retrieval of member graphs based on structure matching. Structure matching of graphs is a known NP-complete pro...

This paper highlights on a method that provides a new prosodic feature called ‘ reliability field’ based on a reliability function of the fundamental frequency ( ). The proposed method does not employ any correction process for estimation errors that occur during automatic extraction. By applying this feature as a score function for prosodic analyses like prosodic structure estimation or superp...

Recovering 3D objects from 2D photos is an important application in the areas of computer vision, computer intelligence, feature recognition, and virtual reality. This paper describes an innovative and systematic method to integrate automatic feature extraction, automatic feature matching, manual revision, feature recovery, and model reconstruction as an effective recovery tool. This method has...

Remote sensing image automatic registration technology is one of the image processing technologies that have been developed rapidly in recent years, and automatic matching of control points is the core work of the automatic registration. Considering the influence of the cloud points and the phenomenon of uneven distribution of control points in AVHRR images, An automatic matching method of cont...
