Image Feature Extraction: Shape, Color, and Texture Descriptors
Shape Descriptors
Contour-Based Shape Descriptors
| Descriptor | Description |
|---|---|
| Shape Signature | Represents the shape of an object as a one-dimensional function extracted from contour points. Examples include distance to centroid, tangent angle, curvature, or arc length. It provides a compact representation for shape analysis and matching. |
| Convex Hull | Defines the smallest convex polygon enclosing the shape. It simplifies complex shapes by excluding concavities, providing a more generalized outline. Useful for |
Key Concepts in Genetics: Gene, Locus, and Allele
Key Concepts in Genetics
The Gene
A gene is organized in a linear sequence of nucleotides in the molecule of DNA (or RNA in the case of some viruses), which contains the information necessary for the synthesis of a macromolecule with specific cellular function, usually proteins, but also mRNA, rRNA, and tRNA.
The Locus
In biology, a locus is a fixed position on a chromosome, the position of a gene or a genetic marker. A variant of the DNA sequence at a given locus is called an allele. The ordered list

Non-Discrimination Principles in WTO Services Trade
Non-discrimination in services under international trade law, specifically within the World Trade Organization (WTO), is governed by two key principles:
- Most-Favored-Nation (MFN) Treatment: Countries must treat all WTO members equally, meaning any favorable treatment given to one member must be extended to all others.
- National Treatment: Foreign services and service providers must be treated no less favorably than domestic ones once they have entered
Spanish Crisis, Dictatorship, Republic, and the Road to WWII
Crisis of the Spanish Restoration and Dictatorship (1900-1931)
In the early decades of the twentieth century, the political system of the Restoration entered its final crisis. This crisis was manifested in:
- Popular Uprisings: Notably the Tragic Week in Barcelona.
- General Strikes: The government managed to suppress strikes and negotiate with the military.
- Government Instability: 13 governments were formed in rapid succession.
- Rural Demonstrations: The Bolshevik Triennium (1918–1922) saw land occupations.

Understanding Health Consciousness
Health consciousness is the degree to which an individual is aware of, interested in, and actively monitors their own health while making lifestyle choices to maintain or improve their well-being. It involves a mindset where health considerations—encompassing physical, mental, and social well-being—are integrated into daily decisions about diet, exercise, stress management, and consumption habits.
Defining Health Consciousness
Health consciousness is a psychosocial

1. Sociology and Social Groups
Sociology is the scientific study of human social behavior, examining how people interact in groups ranging from small personal units to large institutions.
Primary Social Groups
- Small, intimate, face-to-face groups (micro level).
- Primary agents of socialization.
- Fulfill emotional needs and shape identity.
- Examples: family, close friends, married couples.
- Members are allowed into intimate space (0–50 cm).
Secondary Social Groups
- Large, formal, impersonal groups (macro level)

Merge Sort Implementation
The mergeSort method recursively divides the array and then merges the sorted halves.
public static void mergeSort(int[] array) {
int length = array.length;
if (length <= 1)
return;
int middle = length / 2;
int[] leftArray = new int[middle];
int[] rightArray = new int[length - middle];
int j = 0;
for (int i = 0; i < length; i++) {
if (i < middle)

The Many Forms of Deception
Lying is a common practice; it is something we all do. Sometimes the falsehoods are small, sometimes they are bigger, but deception is always present. In her essay The Ways We Lie, Stephanie Ericsson explains that lying isn’t just one thing—it serves different purposes, such as:
- To protect ourselves.
- To dodge responsibility.
- To make life easier.
The problem is that even the “harmless” lies deteriorate trust and honesty, distort communication, and weaken personal integrity.

Criminological Paradigms
- Interactionism
- Critical Theory
Key Principles of Labeling Theory
The focus is on what happens after the action, not what preceded or caused the action.
Primary Deviance
- Occasional or situational behavior that may be excused or rationalized by the actor or the audience.
- The initial act of deviance that goes relatively unpunished.
Secondary Deviance
- Deviant behavior triggered by social reactions that follow primary deviance.
- Deviance that occurs after a person is labeled criminal.

Functions and Nature of the State
In political science, understanding the boundaries and functions of the State is essential, as the term is often colloquially confused with “government,” “society,” or “nation.”
Primary Functions of the Modern State
The modern state serves two primary categories of functions: Essential (Compulsory) and Welfare (Optional).
Essential Functions
These are required for the very survival and identity of the state:
