PRMLT
Matlab code of machine learning algorithms in book PRML
This Matlab package implements machine learning algorithms described in the great textbook: Pattern Recognition and Machine Learning by C. Bishop (PRML). It is written purely in Matlab language. It is self-contained. There is no external dependency. This package requires Matlab R2016b or latter, since it utilizes a new Matlab syntax called Implicit expansion (a.k.a. broadcasting). It also requires Statistics Toolbox (for some simple random number generator) and Image Processing Toolbox (for reading image data). ... -

TechnicalIndicators
A javascript technical indicators written in typescript
A javascript technical indicator written in typescript with pattern recognition right in the browser. Every indicator has a static method calculated which can be used to calculate the indicator without creating an object. Initialize the indicator with the available price value. Get results for initialized values. Use nextValue to get the next indicator values for further tick. This uses regular javascript numbers, so there can be rounding errors that are negligible for a technical indicators, you can set precision by using the below config. ... -

Text Picker
Use your camera to identify and pick texts such as serial numbers.
The TextPicker uses your camera and optical character recognition to extract a text from what your camera sees. You must type a regex pattern (or choose one from the several pre-configured regex pattern). Only texts that match the pattern will be picked. This software is mainly used for recognizing serial numbers in currencies of the world. You can make other similar uses as well. -

DGRLVQ
Dynamic Generalized Relevance Learning Vector Quantization
Some of the usual problems for Learning vector quantization (LVQ) based methods are that one cannot optimally guess about the number of prototypes required for initialization for multimodal data structures i.e.these algorithms are very sensitive to initialization of prototypes and one has to pre define the optimal number of prototypes before running the algorithm. If a prototype, for some reasons, is ‘outside’ the cluster which it should represent and if there are points of a different... -

The code consists of an automatic segmentation system that is based on the Hough transform, and is able to localize the circular iris and pupil region, occluding eyelids and eyelashes, and reflections. The extracted iris region was then normalized into a rectangular block with constant dimensions to account for imaging inconsistencies. Finally, the phase data from 1D Log-Gabor filters was extracted and quantized to four levels to encode the unique pattern of the iris into a bit-wise...

This paper represent a development and deployment and/or Implementation of Optical Character Recognition (OCR) to translate images of typewritten or handwritten characters into electronically editable format by preserving font properties. OCR can do this by applying pattern matching algorithm. The Recognized characters are stored in editable format. Thus OCR make the computer read the printed documents discarding noise. Keywords- Optical Character Recognition, Image convert to character, Image cropping.

Fingerprint Recognition System
Fingerprint Recognition System 5.3 - Matlab source code
The proposed filter-based algorithm uses a bank of Gabor filters to capture both local and global details in a fingerprint as a compact fixed length FingerCode. The fingerprint matching is based on the Euclidean distance between the two corresponding FingerCodes and hence is extremely fast. We are able to achieve a verification accuracy which is only marginally inferior to the best results of minutiae-based algorithms published in the open literature. Our system performs better than a... -

DrawPad
Pattern recognition tool for image, pdf and handwritings
The tool is an optical recognition tool which runs in following three mode : 1. Drawing Pad : Here the user can draw a character and the tool will recognize which character it is. 2. Image OCR : Image based OCR tool to recognize text and barcodes present in the image. It also supports saving the OCR output. 3. PDF OCR : PDF OCR is the advanced form of OCR, where PDF is parsed into image and OCR is run on that result. At present, PDF OCR comes with low maturity. -
