چکیده
Vehicle identification based on image processing is the basic key behind this paper. This technology has been obtained world wide attention nowadays due to low cost,flexibility,ease of access,potential towards collision avoidance and accuracy. In most cases the vehicles are identified on the basis of colour,texture,histogram,hue,saturation,contrast etc. Gabor filter obtained from Gaussian filters are mainly used in image processing due to its better performance. But the main drawback of Gabor filters is related to the frequency response. The bandwidth is limited to reduce the DC noise components. Moreover filter banks have to be used. So a novel idea called Log Gabor filter has been suggested to overcome the drawbacks. Log Gabor filters are designed as Gaussian functions on log axis, which is in fact spatial frequency response of visual neurons. The result expected is that the frequency response

Log Gabor Filter Based Feature Detection in Image Verification Application
In recent years due to low-cost, flexibility, and potential toward collision avoidance the Vehicle and Non Vehicle identification based on image processing bring more attention. In particular, vehicle verification is especially challenging on account of the heterogeneity of vehicles in color, size, pose, etc. Image based vehicle verification is usually addressed as a supervised classification p...
متن کاملVehicle Verification Using Log Gabor Filter Based On Video and Number Plate Recognition
Vehicle verification has very importance in this year because of its efficiency to avoid collision and less cost. Vehicle verification is difficult since the vehicle is similar in its color, shape and pose.log Gabor filter is used here as the algorithm to perform this task. Previously Gabor filter had been used. But since it has some drawbacks log Gabor filter introduced. Energy feature is choo...
متن کاملGabor Filter Based Feature Vector for Dynamic Signature Recognition
Dynamic signature recognition is one of the commonly used biometric traits. In this paper we propose use of Gabor filters based feature for verification of dynamic signature. We incorporate the timing information available in the signature along with the Gabor filter response to generate the feature vector. Gabor filters have been widely used for image, texture analysis. Here we present analysi...
متن کاملGabor Filter-based Multiple Enrollment Fingerprint Recognition
Minutiae-based matching techniques have been widely used in the implementation of multiple enrollment fingerprint recognition systems. However, these techniques suffer the difficulty of automatically extracting all minutiae points due to failure to detect the complete ridge structures of a fingerprint. With poor quality fingerprint images, detection of minutiae points as well as describing all ...
متن کاملFingerprint Verification based on Gabor Filter Enhancement
Human fingerprints are reliable characteristics for personnel identification as it is unique and persistence. A fingerprint pattern consists of ridges, valleys and minutiae. In this paper we propose Fingerprint Verification based on Gabor Filter Enhancement (FVGFE) algorithm for minutiae feature extraction and post processing based on 9-pixel neighborhood. A global feature extraction and finger...
