Human Skin Detection in Color Images

Overview of my Bachelor thesis.

The purpose of the thesis is to present a review of the human skin detection datasets and approaches of the state of the art, and then perform a comparative in-depth analysis of the most relevant methods on different databases.

Abstract

Skin detection is the process of discriminating skin and non-skin pixels in an arbitrary image and represents an intermediate step in several image processing tasks, such as facial analysis and biomedical segmentation. Different approaches have been presented in the literature, but a comparison is diffcult to perform due to multiple datasets and varying performance measurements. In this work, the datasets and the state-of-the-art approaches are reviewed and categorized using a new proposed taxonomy. Three different representative skin detector methods of the state of the art are selected and thoroughly analyzed. This approaches are then evaluated on three different state of the art datasets and skin tones sub-datasets using multiple metrics. The evaluation is performed on single and cross dataset scenario to highlight key differences between methods, reporting also the inference time. Finally, the results are organized into multiple tables, using the related figures as an assistance tool to support the discussion. Experimental results demonstrate the strength and weaknesses of each approach, and the need to involve multiple metrics for a fair assessment of the method’s aspects.

Setup

This website is built using Docusaurus 2, a modern static website generator.

Installation

$ yarn

Local Development

$ yarn start

This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.

Build

$ yarn build

This command generates static content into the build directory and can be served using any static contents hosting service.

Deployment

Using SSH:

$ USE_SSH=true yarn deploy

Not using SSH:

$ GIT_USER=<Your GitHub username> yarn deploy

If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the gh-pages branch.
