The pattern matching algorithm involves the following steps: The input video frame and the template are reduced in size to minimize the amount of computation required by the matching algorithm. Normalized cross correlation, in the frequency domain, is used to find a template in the video frame. The location of the pattern is determined by ...
Patterns to search and match text - MATLAB
https://www.mathworks.com/help/matlab/ref/pattern.html
A pattern defines rules for matching text with text-searching functions like contains, matches, and extract.You can build a pattern expression using pattern functions, operators, and literal text. For example, MATLAB ® release names, start with "R", followed by the four-digit year, and then either "a" or "b".Define a pattern to match the format of the release names:
Determine if pattern matches strings - MATLAB matches
https://www.mathworks.com/help/matlab/ref/matches.html
Create a pattern that matches the hexadecimal numbers. To match a single hexadecimal digit, specify a pattern that matches any digit, any capital letter A-F, or any lowercase letter a-f.Then, specify a pattern that begins with 0x and is followed by any number of hexadecimal digits.

In the pattern matching technique, it finds the exact matches among input data with historical patterns. For instance: we can say the search options in word processors and text editor which look for the same match of input text data.
Build Pattern Expressions - MATLAB & Simulink
https://www.mathworks.com/help/matlab/matlab_prog/build-pattern-expressions.html
Patterns are a tool to aid in searching for and modifying text. Similar to regular expressions, a pattern defines rules for matching text. Patterns can be used with text-searching functions like contains, matches, and extract to specify which portions of text these functions act on. You can build a pattern expression in a way similar to how you ...
Match regular expression (case sensitive) - MATLAB regexp
https://www.mathworks.com/help/matlab/ref/regexp.html
The regexpi function uses the same syntax as regexp, but performs case-insensitive matching. matchWithRegexpi = regexpi (str,expression, 'match') matchWithRegexpi = 1x2 cell {'UPPERCASE'} {'lowercase'} Alternatively, disable case-sensitive matching for …
