Biometrics is an important application of digital image processing of biometric modalities. There are several types of biometric security technologies such as face recognition, iris recognition, fingerprint matching etc. However, there are some prominent challenges in all biometrics dealing with single modality such as reliability, robustness etc. Therefore, multimodal biometrics is recommended, which involves more than one modality in the system. AADHAAR card is an example of multimodal biometrics.
Multimodal biometrics aims at increasing the reliability of biometric systems. In this research, four traits such as face, ear, iris and foot were used and worked on matching score level and decision level to get advantage of the multimodal approaches. The work was tested over self created database of 100 persons. Different classifier approaches for different modalities were applied; principle component analysis for face, eigen images for ear, hamming distance based technique for iris and modified sequential Haar transform for foot traits. Each biometric trait processed its information independently to calculate weights of individuals. The fusion scheme was applied on all possible combination of traits and the matching score was calculated. The integrated results of different biometric traits increased the recognition performance of the multimodal biometric system considerably
Biometric identification is a mandatory tool to secure digital information for various industrial, government, commercial, and security applications. Face recognition is a distinct problem and lacks a unique solution applicable to all situations. Face recognition is not effective in identifying individuals in conditions, when a person is using glasses, hats or has a beard etc. Alternative technologies like Iris and retinal scan biometric techniques need sophisticated equipment, which is not financially viable for all applications. Voice recognition methods have low accuracy and are affected by situations where a change in a person's voice due to illness like cold render absolute identification inaccurate. This paper proposes a biometric method implementing multiple techniques i.e., both face and voice recognition technique as an effective identification tool. Identification process using combined biometric methods makes a foolproof security system, thereby leaving no scope for error. A comprehensive assessment of the performance accuracy of several algorithms like Principal Component Analysis (PCA), Fisher Linear Discriminant Analysis (FLD), Dynamic Time Warping (DTW), Support Virtual Machines (SVM), Neural Networks (NN) implemented in face and voice recognition were studied and then corresponding performance accuracy was reviewed. A new technique has been proposed using these performance accuracy results which would help provide the best hybrid method. The proposed hybrid biometric identification method is a viable solution for industries or areas with need for high security of their data systems.
RGB (Red, Green, Blue) color scale image to Gray scale image color conversion is very useful and application oriented in the digital image processing world. In this paper, the authors have presented a basic method for the grayscale images to color image conversion by transferring the color elements between a source input, RGB color image and a destination, the gray scale image. The methods compared here are based on matching luminance and color information between the gray images.
The de-corrected color space of image is chosen to provide color to the pixel gray image, which is a basic and simple algorithm. Thus, the color-space with de-correlated technique is an extremely vital tool for manipulating the pixel of color images during this work. Colorization of the gray scale image pixel is obtained here by matching the texture options of gray image with coloring options of the windows of the colored image elements, then mean and variance are imposed on the info points during this simple operation. Thus the required output images are obtained for the acceptable input images.
The gray-scale image pixel and reference-colored image pixel uses YCbCr (Y-Luma Component; Cb, Cr - Bluedifference and Red - Difference Chroma Components) pixel space for the processing of the image pixels in this elements of color-space component data, which is for the colorization of the gray-scale pixel image. The output of system is obtained by colorization using a popular method of using the mean and standard deviation technique in lab. All the methods utilized in this gray-scale image colorization was an automatic image colorization process, requiring two factors of the images i.e. gray-scale image as source and pixel of color image layers as the destination of image. After undergoing histogram analysis, the colors of the source image elements are successfully transferred to the destination image. The closer the luminance image pixel data of both images, the easier the transfer process becomes.
Deep learning and Neural Network algorithms are a branch of Machine learning that can automatically identify patterns in the data, and then use the uncovered patterns to predict future data, or to perform other alternative kinds of decision making under unreliability. Neural Networks is a method of computing, which is based on a collection of large number of neural units, which acts as a biological brain and solve problems with large clusters of biological neurons connected by axons. Deep Learning algorithms are used to model high level abstractions in data. Digit Recognition is a combination of Deep Learning and Neural Network algorithms, which uses TensorFlow tool as an interface to develop a model. This paper describes the recognition of handwritten scanned digits by a system and displays the output as digital numbers by using Machine Learning methods with the help of TensorFlow tool.
