Introduction


String Matching:
string matching is an algorithm that try to find a string of length m(called pattern)
from a string of length n (called text).
Text :- Text is an array T of length n.

Pattern:- Pattern is an array P of length m , where m≤n.

Finite alphabet :- It is a finite set of characters . The elements are taken from T and P.It is denoted by Σ.
Eg:- Σ = {0,1}
Σ = {a ....etc

hi,this is kavitha im doing a project on edge adaptive image steganography based on lsb matching revisited,im having abstract and requirements ,i need source code for my project
ABSTRACT :

The least-significant-bit (LSB)-based approach is a popular type of steganographic algorithms in the spatial domain. However, we find that in most existing approaches, the choice of embedding positions within a cover image mainly depends on a pseudorandom number generator without considering the relationship between the image cont ....etc

Multispectral (MS) fingerprint imaging systems use different wavelengths of light to illuminate the surface and the subsurface layers of the finger skin and capture the reflected light. The resulting fingerprint images and the combination of these images provide more discriminatory and robust information about the characteristics of the fingerprint than those from a TIR based optical fingerprint sensor ....etc

Automatic Target Recognition by
Matching Oriented Edge Pixels

Clark F. Olson and Daniel P. Huttenlocher



Abstract—This paper describes techniques to perform efficient
and accurate target recognition in difficult domains. In order to
accurately model small, irregularly shaped targets, the target objects
and images are represented by their edge maps, with a local
orientation associated with each edge pixel. Three-dimensional
objects are modeled by a set of two-dimensional (2-D) views of
the obj ....etc

ABSTRACT

Template matching is an object detection technique in image processing to find small parts of an image which match a template image. There are many methods one can adopt for this purpose.

Matching can be Template based, in which case every pixel that contributes to the template may be matched against every pixel of the image using any means of comparison (eg. SAD, SSD, cross-correlation), or it can me Feature based, where the matching is on the basis of some strong features that the template ma ....etc

1 Abstract
DotStar is a tool for very fast regular expression matching. It is an innovative algorith-
mic solution that compiles user provided regular expressions into a compact automaton using
a sequence of more manageable intermediate representations. The resulting automaton can
search using a single pass without bac ....etc
