Classification of Epithelial Tissues: Stratified Epithelium01:29

Classification of Epithelial Tissues: Stratified Epithelium

9.8K
Stratified epithelium consists of several stacked layers of cells. They provide the durability to withstand constant physical and chemical attacks. Stratified epithelium is named after the shape of the most apical layer of cells. Stratified squamous epithelium is the most common type found in the human body. In this tissue, the apical cells are squamous, whereas the basal layer contains either columnar or cuboidal cells. The basal cells divide to form new daughter cells, which gradually become...

Classification of Epithelial Tissues: Overview

14.5K
Epithelial tissues are classified according to the shape of the cells and the number of cell layers formed. Cell shapes can be squamous (flattened and thin), cuboidal (square-like, as wide as it is tall), or columnar (rectangular, taller than it is wide). Additionally, the nucleus shape helps identify the type of epithelial cells. Squamous cells have flattened disc-shaped nuclei, cuboidal cells have spherical nuclei, and columnar cells have elongated nuclei.
Based on the number of cell layers,...

Classification of Connective Tissues

11.2K
The connective tissues have different properties and functions in the human body. They are broadly categorized into proper, supporting, or fluid connective tissues.
Connective Tissue Proper
Connective tissue proper is the most abundant class of connective tissues. As its name implies, it predominantly connects different tissues in the body. Depending on the cell types, ground substance, viscosity, and fiber types in the ECM, connective tissue proper is further categorized into loose and dense....

Skin Cancer01:30

Skin Cancer

4.5K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Classification of Leukocytes01:30

Classification of Leukocytes

2.5K
Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...

Classification of Systems-I

292
Linearity is a system property characterized by a direct input-output relationship, combining homogeneity and additivity.
Homogeneity dictates that if an input x(t) is multiplied by a constant c, the output y(t) is multiplied by the same constant. Mathematically, this is expressed as:

Area of Science:

  • Dermatology and Artificial Intelligence
  • Medical Imaging Analysis
  • Computational Pathology

Background:

  • Early detection of skin cancer is crucial for effective treatment and preventing metastasis.
  • Accurate computer-aided diagnosis systems are needed to support clinicians in identifying malignant skin lesions.
  • Deep learning shows promise for analyzing complex medical images like skin lesions.

Purpose of the Study:

  • To develop and evaluate a novel skin lesion classification system utilizing deep learning and collective intelligence.

  • To create an ensemble model that combines multiple convolutional neural networks for improved diagnostic performance.

Main Methods:

  • A collective intelligence-based system was designed, integrating multiple convolutional neural networks (AlexNet, GoogLeNet, MobileNet-V2, Xception, ResNet, InceptionResNet-V2, DenseNet201).
  • Networks were trained on the HAM10000 dataset for skin lesion classification.
  • A weight matrix was derived from individual network performances to create a multi-network ensemble system with a collective decision block for fused predictions.

Main Results:

  • The proposed collective intelligence system achieved a validation accuracy approximately 3% higher than the best-performing individual convolutional neural network.
  • The ensemble approach demonstrated enhanced performance in classifying various skin lesions, including melanoma.
  • Individual network performances were analyzed to assign weights for the ensemble decision-making process.

Conclusions:

  • The developed collective intelligence system offers a more accurate approach to skin lesion classification compared to individual deep learning models.
  • This system has the potential to significantly aid medical professionals in the early and accurate detection of skin cancer.
  • Further validation and clinical integration of this AI-driven diagnostic tool are warranted.
