Summary
This study introduces a texture segmentation method using correlation coefficients and a split-and-merge algorithm. It refines segmentation by grouping small regions based on gray levels for improved texture analysis.
Area of Science:
- Computer Vision
- Image Processing
- Pattern Recognition
Background:
- Texture segmentation is crucial for image analysis.
- Existing methods may struggle with uniform texture identification.
- Hierarchical image representations offer potential for efficient segmentation.
Purpose of the Study:
- To develop and evaluate a novel texture segmentation algorithm.
- To utilize correlation coefficients for identifying uniform texture regions.
- To improve segmentation accuracy through a hierarchical approach and post-processing.
Main Methods:
- Correlation coefficients were evaluated on a quadratic picture tree (pyramid).
- A split-and-merge algorithm was employed for preliminary segmentation based on texture uniformity.
- A grouping algorithm, region adjacency graph, and small region elimination refined the segmentation.
Main Results:
- The split-and-merge approach successfully identified and segmented regions based on texture similarity.
- The grouping algorithm and small region elimination enhanced the final segmentation quality.
- The method demonstrated effective texture segmentation on example images.
Conclusions:
- The proposed method effectively segments images based on texture using correlation coefficients.
- The hierarchical split-and-merge strategy combined with post-processing yields robust texture segmentation.
- This approach offers a reliable way to analyze texture in image processing applications.

Shape and Texture of Coarse Aggregate
Aggregate shape is classified based on the relative sharpness or roundness of the edges and corners. This classification includes categories like rounded, angular, elongated, and flaky, each with specific characteristics. Rounded aggregates, fully shaped by attrition, are typical of river or seashore gravel, while angular aggregates, such as crushed rock, have well-defined edges. Aggregates that are elongated and flaky are less desirable, as they can reduce the workability and strength of...
Correlation
In statistics, two variables are said to be correlated if the values of one variable are associated with the other variable. Depending on the relationship between two variables, correlation can be of three types– positive correlation, negative correlation, and zero correlation.
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:

Correlation and Regression
In statistics, correlation describes the degree of association between two variables. In the subfield of linear regression, correlation is mathematically expressed by the correlation coefficient, which describes the strength and direction of the relationship between two variables. The coefficient is symbolically represented by 'r' and ranges from -1 to +1. A positive value indicates a positive correlation where the two variables move in the same direction. A negative value suggests a negative...
Correlations
Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...
Coefficient of Correlation
The correlation coefficient, r, developed by Karl Pearson in the early 1900s, is numerical and provides a measure of strength and direction of the linear association between the independent variable x and the dependent variable y.
If you suspect a linear relationship between x and y, then r can measure how strong the linear relationship is.
What the VALUE of r tells us:
The value of r is always between –1 and +1: –1 ≤ r ≤ 1.
The size of the correlation r indicates the strength of the linear...
