Classifying Matter by Composition

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures. 
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated. 
A mixture is composed of two or...

Classifying Matter by State

102.7K
Chemistry is the study of matter and the changes it undergoes. Matter is anything that has mass and occupies space. Matter is all around us; the air, water, soil, mountains, even our bodies are all examples of matter. Matter is divided into three states — solid, liquid, and gas — that are commonly found on earth. The fourth state of matter, plasma, occurs naturally in the interiors of stars.

Root Mean Square

If in an experiment, data values have a probability of being both positive and negative, neither the arithmetic mean, the geometric mean, nor the harmonic mean can be used to calculate the central tendency of the data set. In particular, if the positive and negative values are equally likely, the arithmetic mean is close to zero.
For example, consider the velocity of gas molecules in a container. The gas molecules are moving in different directions, which might impart positive and negative...

Cis-regulatory Sequences02:02

Cis-regulatory Sequences

11.6K
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Chi-square Analysis

43.7K
The chi-square test is a statistical hypothesis test. It is used to check whether there is a significant difference between an expected value and an observed value. In the context of genetics, it enables us to either accept or reject a hypothesis, based on how much the observed values deviate from the expected values.
The chi-square test was developed by Pearson in 1990.
The first step of performing a Chi-square analysis is to establish a null hypothesis, which assumes that there is no real...

Area of Science:

  • Computer Vision
  • Machine Learning
  • Pattern Recognition

Background:

  • Moving object detection is crucial for object tracking in video analysis.
  • Accurate detection and classification of objects in video sequences remain a challenge.

Purpose of the Study:

  • To detect and classify moving objects in video sequences.
  • To evaluate and compare the performance of different classification algorithms for this task.

Main Methods:

  • Video sequences were collected from public datasets and individual frames were extracted.
  • A novel background subtraction method was applied after frame pre-processing.
  • Features were extracted using Local Binary Pattern (LBP) and grey level co-efficient.
  • Classifiers including Support Vector Machine (SVM), Partial Least Squares (PLS), and Probabilistic Neural Network (PNN) were employed.

Main Results:

  • The Partial Least Squares (PLS) classifier demonstrated superior classification accuracy compared to SVM and PNN.
  • The PLS classifier required a longer computation time.

Conclusions:

  • Feature extraction using LBP and grey level co-efficient is effective for object detection.
  • PLS offers high accuracy for moving object classification in videos, balancing performance and computational cost.
