This technical seminar presentation summarizes image processing in forensic science. It introduces image processing and forensics, then outlines the contents to be covered, including the objectives and categories of forensic image analysis, such as photo comparison, content analysis, authentication and enhancement. Methodologies for forensic image analysis are also presented, along with conclusions that such analysis can aid legal investigations but remains a challenging field. References are provided.

3. What is Image Processing?
Image processing is a method to perform some
operations on an image, in order to get an enhanced
image or to extract some useful information from it.
 It is a type of signal processing in which input is an
image and output may be image or
characteristics/features associated with that image

4. What is Forensic?
 Forensic science is the application of science and
technology to the criminal justice system.

5. INTRODUCTION:
Image Processing in Forensic Science is used to make
clear the content of an image in legal matters.
forensic experts need to perform mainly two tasks such as
image interpretation and image examination.

6. FORENSIC IMAGE ANALYSIS:
The objective of forensic Image analysis is to recognize the
features, similarity measure components in the image and to
extract information from them for comparison and/or analysis.
There are four categories in forensic image analysis. They
are:
1. Photo image comparison
2. Image Content Analysis (ICA)
3. Image Authentication
4. Image Enhancement and Restoration

7. PHOTO IMAGE COMPARISION:
Photo comparison deals with the similarities among the given
query image and known image.

IMAGE CONTENT ANALYSIS:
ICA is the process of drawing conclusions about
an image.

9. IMAGE AUTHENTICATION:
Image Authentication is the verification of the information content
whether it is original image or manipulated one.

IMAGE ENHANCEMENT AND RESTORATION:
Enhancement and clarification usually refers to correcting
image blur, reducing image noise, or adjustments to brightness
and contrast to bring out details that are otherwise difficult to
discern.

Conclusion & Future Scope:
forensic image analysis is very challenging field of research with
the continuous growth of interest and increasing security
requirements for the development of the modern society.
 The computer assisted image analysis will aid the forensic experts,
legal
experts, and policy makers in deriving appropriate conclusions for
the investigation.
