Techniques Used For Extracting Useful Information From Images

Thus our proposed optimal feature subset selection based on multi-level feature subset selection produced better results based on number of subset feature produced and classifier performance. The future scope of the work is to use these features to annotate the image regions, so that the image retrieval system can retrieve relevant images based on image semantics.

Abstract—Automatic recognition of people is a challenging problem which has received much attention during recent years due to its many applications in different fields. Face recognition is one of those challenging problems and up to date, there is no technique that provides a robust solution to all situations. This paper presents a technique for human face recognition. A self-organizing program is used to identify if the subject in the input image is “present” or “not present” in the image database. Face recognition with Eigen values is carried out by classifying Eigen values in both images. The main advantage of this technique is its high-speed processing capability and low computational requirements, in terms of both speed, accuracy and memory utilization. The goal is to implement the system for a particular face and distinguish it

In the present contemporary era, facial recognition technologies are being installed by the companies in an extensive sense that surely reflects a continuum of growing hi-tech superiority and complexity. At the most ordinary level, facial detection is done by this technology which means that a photo is just detected and located for a face ("Facing Facts: Best Practices for Common Uses of Facial Recognition Technologies," 2012).

Out of all of my interests in computer technology, it is also the topic of my graduation thesis. Facial recognition has recently accomplished great achievements since its acknowledgment rate at many institutions has nearly reached 100%, but there are still many obstacles. One of them is the difficulty in recognizing children, understanding the meaning behind the picture and issues with age variation. The performance of most facial recognition algorithms significantly vary with different sample sets. My research is preliminarily and targeted to the aforementioned

Images with higher similarity than threshold are returned as an output. System which uses the content of the object for Information Retrieval is the CBIR.

Image processing usually refers to digital image processing, but optical and analog image processing also are possible. This article is about general techniques that apply to all of them. The acquisition of images (producing the input image in the first place) is referred to as imaging.

Data mining is a popular technology for extracting interesting information for multimedia data sets, such as audio, video, images, graphics, speech, text and combination of several types of data set. Multimedia data are unstructured data or semi-structured data. These data are stored in multimedia database, multimedia mining which is used to find information from large multimedia database system, using multimedia techniques and powerful tools. This paper analyzes about the use of essential characteristics of multimedia data mining, retrieving information is one of the goals of data mining and different issues have been discussed. The current approaches and techniques are explained for mining multimedia data. In this paper applications and models of multimedia mining are discussed clearly. Nowadays Multimedia mining has become popular field in research area.

measures between brightness distributions. Experiments performed on picture with 3 faces display that the 3 bin-by-bin measures along with Minkowski-shape distance, Chi-rectangular distance and Bhattacharyya reserve provide a real positive value of 56.76%, 59.46% and 48.65% respectively, while cross-bin measures such as Earth Movers Distance (EMD), Match distance and Kolmogorov-Smirnov distance deliver decrease genuine fantastic rates of 32.43%, 32.43% and 37.44r% respectively. Results of threshold based totally method for picture with faces display that the three bin-by way of-bin measures which includes Minkowski-shape distance, Chi-square distance and Bhattacharyya distance deliver a true wonderful price of sixty three.16%, 63.16% and 60.53% respectively, whereas go-bin measures which

Recently, appearance-based face recognition has received tons of attention. In general, a face image of size n1 × n2 is delineating as a vector within the image house Rn1 × n2. We have a tendency to denote

The solutions provided in this research work are more compatible for retrieving images from natural and photographic image databases and use an amalgamation of image processing and machine learning algorithms to perform retrieval in a fast manner while improving both the fraction of retrieved images that are relevant to the find and fraction of the images that are relevant to the query image that are successfully retrieved.

Image retrieval is extracting an image out of particular larger data set. The traditional image retrieval is as shown in the fig below where the query image whose image is to be retrieved is carried the feature extraction process and compared the feature extracted image in the database and then compared. This retrieved and database image if matched

This representation of Haar-Like Feature was used to find and select features according to pixel intensities and not by pixels values. Haar-like feature can be calculated using the scalar product between the input image and some Haar-like templates [14].

The Report presents a hybrid neural network solution, which compares favorably with other methods and recognizes a person within a large database of faces. These neural systems typically return a list of most likely people in the database. Often only one image is available per person. First a database is created, which contains images of various persons. In the next stage, the available images are trained and stored in the database. Finally it classifies the authorized person’s face, which is used in security monitoring system. Faces represent complex, multidimensional, meaningful visual stimuli and developing a computational model for face recognition is difficult. Face has certain distinguishable landmarks that are the peaks and valleys that sum up the different facial features. There are about 80 peaks and valleys on a human face. The following are a few of the peaks and valleys that are measured by the software:

Segmenting or dividing a digital image into region of interests or meaningful structures in general plays a momentous role in quite a few image processing tasks. Image analysis, image visualization, object representation are some of them. The prime objective of segmenting a digital image is to change its representation so that it looks more expressive for image analysis. During the course of action in image segmentation, each and every pixel of the image segmentation is assigned a label or value. The pixels that share the same value also share homogeneous traits. The examples can include color, texture, intensity or some other features. Image segmentation can be defined as the technique to divide the an image f (x, y) into a non empty subset f1, f2, ...., fn which is continuous and disconnected. This step contributes in feature extraction. There are quite a few applications where image segmentation plays a pivotal role. These applications vary from image filtering, face recognition, medical imaging
