Implementation of a palmprint recognition system

SAX is the first symbolic representation for time series that allows for dimensionality reduction and indexing with a lower-bounding distance measure. In classic data mining tasks such as clustering, classification, index, etc.

In addition, the representation allows researchers to avail of the wealth of data structures and algorithms in bioinformatics or text mining, and also provides solutions to many challenges associated with current data mining tasks.

Implementation of a palmprint recognition system

One example is motif discovery, a problem which we defined for time series data. There is great potential for extending and Implementation of a palmprint recognition system the discrete representation on a wide class of data mining tasks.

Edward Tufte was kind enough to mention that SAX allows a sparkline like visualization of data. The relevant paper is this one [ pdf ]. Download this zip file for the code and details.

Here is a video of Dr. Keogh giving a talk at Google about using SAX for various problems, including shape mining. Visit the iSAX page.

How to find us

Try this Matlab code snippet: As an example, we can find similarity searches using edit distance over 10, time series in 50 milliseconds. I have had tried several different approaches, but so far Ive had the most success applying the SAX-bitmap-based approach. Data Mining Applications in the Automotive Industry.

Lin and Lin To circumvent the limitations of our previous work, we now rely on a similarity measure that is based on a recent technique called symbolic aggregate approximation SAX. SAX based VizTree is.

SAX, and more recently iSAX ,has gained traction as the de facto representation for time series in the largespace of representation choice. In order to symbolize a street data, we utilize the SAX approach.

We have decided to use SAX to detect sophisticated attack tools. SAX is a recent and popular method with interesting proven properties. Amy McGovern et al. SAX representation of abstracted data makes analysis of anterior-posterior center of pressure more easy and accurate. Our Symbolic Transformation based on SAX method can be use to discover novel gene relations by mining similar subsequences in time-series microarray data.

It also allows real valued data to remain the original characteristics with only an infinitesimal time and space overhead SAX demonstrates some promising properties for the field of anomaly detection in a marine engine.

Morgan, Liu, Turnbull, and Brown By using SAX with the sensor network data, we are able to detect such complex patterns with good accuracy. SAX is a very mature and robust solution for mining time-series data. Zoumboulakis and Roussos we apply the SAX based motif discovery approach the analysis of responses obtained by tactile stimulation of different body areas.

Duda, Nurnberger and Stober Makio, Tanaka, and Uehara symbolic aggregate approximation SAX outperform other dimensionality reduction techniques like singular value decomposition or discrete fourier transform SVD, DFT for time series data.

Cohen, Bjornsson, Temple, Banker, and Roysam. PAMI we apply a technique that has demonstrated success with the interpretation of univariate data, named SAX to visualize patterns that may differentiate between medical conditions such as renal and respiratory failure.

Ralph Krieger We argue that symbolic representations in particular SAX are comparatively superior in the data analysis of time series. Field, StirlingNaghdy and Pan. ACRA We will often apply this symbolization approach, using the methodology of SAX, with a primary goal of reducing the number of tunable parameters to increase the robustness of the approach Bollt and Skufca We have shown that a SAX method is particularly useful.outline of palmprint recognition systems is presented in section 2.

Palmprint image preprocessing steps are mentioned in Section 3. The other phases of the palmprint recognition like feature. Fingerprint identification, known as dactyloscopy, or hand print identification, is the process of comparing two instances of friction ridge skin impressions (see Minutiae), from human fingers or toes, or even the palm of the hand or sole of the foot, to determine whether these impressions could have come from the same grupobittia.com flexibility of friction ridge skin means that no two finger.

Biometric authentication such as palmprint recognition is the strongest of the personal authentication technologies designed to prevent such misuse.

In biometric authentication, when compared with a local authentication model, a remote authentication model has several advantages such as direct authentication and authentication levels. CHAPTER -VI. 6. CONCLUSION & SCOPE OF FUTURE WORK. There are some key aspects to discuss about this thesis in general.

First, it is important to mention that the main objective of this work - implementation of a palmprint recognition system - was successfully accomplished. In the palmprint recognition algorithm used in our system, the position of the authenticated image is adjusted using the enrolled data.

Thus, the flow of sending the enrolled data from the authentication server to the cellular phone is included in step 3 of the matching procedure of the proposed system.

When a cellular phone is lost or stolen, it may be used improperly or the personal information may be stolen from it by a malicious user. Biometric authentication such as palm-print recognition is the strongest of the personal authentication technologies designed to prevent such misuse.
