Shape and Texture of Coarse Aggregate01:25

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...

Introduction to Scalers

Many familiar physical quantities can be specified completely by giving a single number and the appropriate unit. For example, "a class period lasts 50 min," or "the gas tank in my car holds 65 L," or "the distance between the two posts is 100 m." A physical quantity that can be specified completely in this manner is called a scalar quantity. The word "scalar" is a synonym for "number." Time, mass, distance, length, volume, temperature, and energy are some examples of scalar quantities.

Scaling01:26

Scaling

In designing and analyzing filters, resonant circuits, or circuit analysis at large, working with standard element values like 1 ohm, 1 henry, or 1 farad can be convenient before scaling these values to more realistic figures. This approach is widely utilized by not employing realistic element values in numerous examples and problems; it simplifies mastering circuit analysis through convenient component values. The complexity of calculations is thereby reduced, with the understanding that...

Area of Science:

  • Computer Vision
  • Image Processing
  • Machine Learning

Background:

  • Texture image classification accuracy is often limited by image scale variations.
  • Existing scale-invariant methods can be complex or computationally intensive.

Purpose of the Study:

  • To propose an alternative approach for texture image classification that addresses scale dependency.
  • To enhance texture recognition and classification by estimating and utilizing an effective image scale.

Main Methods:

  • Utilizing the correlation distance between pixels as a metric for texture image scale.
  • Investigating the performance of texture classification within the coordinated cluster representation (CCR) feature space.
  • Analyzing the impact of image scale and scanning window size in the coordinated cluster transform.

Main Results:

  • An optimal classification efficiency (up to 100%) was achieved in the CCR feature space.
  • This optimal efficiency was obtained by adjusting the image scale and/or the scanning window size.
  • The proposed method demonstrates effective texture image recognition and classification.

Conclusions:

  • Estimating an effective image scale is a viable strategy to overcome scale-related limitations in texture classification.
  • The coordinated cluster representation (CCR) combined with scale adjustment offers a robust framework for high-accuracy texture classification.
  • Optimizing image scale and scanning window parameters is crucial for maximizing classification performance.
