Interpol review of imaging and video 2016–2019

Abstract

This review paper covers the forensic-relevant literature in imaging and video analysis from 2016 to 2019 as a part of the 19th Interpol International Forensic Science Managers Symposium. The review papers are also available at the Interpol website at: https://www.interpol.int/content/download/14458/file/Interpol%20Review%20Papers%202019.pdf .

Badminton Smashing Recognition through Video Performance by using Deep Learning

“…The CNN classifier consisting of two convolutional layers, two pooling layers, a fully connected layer, and a softmax layer can be used to divide the sports activities into table tennis, tennis, badminton, golf, batting baseball, shooting basketball, volleyball, dribbling basketball, running, and bicycling, respectively [3]. The convolutional layer is the core building block of a Convolutional Neural Network (CNN) [4]. The layer's parameters consist of kernels that have a small receptive field.…”

A Systematic Literature Review on the Usage of Digital Photography at Crime Scene Investigation Process

“…[16] described photographs as a digital component containing information that can be used to identify the perpetrator and the victim and relate to the incident that occurred during the investigation process. In digital photography, three coherent, recorded, validated, and inter-connect knowledge components form the knowledge chain in each investigation stage: methods and tools [2]. In medical, digital images are used to describe clinical findings, operational measures, or postoperative outcomes for medical education and record-keeping [12].…”

“…[12] describe the power of a picture piece has the potential to solve a case, and a picture can give an idea of the scene even if we are not in the place. However, according to [2], photos, are only tools in investigation which still requires other corroborative evidence for identification. Geradts's opinion does not represent the overall thinking of researchers when [1] defending the importance of photographs serve to clarify the scene of a crime and present the visual evidence in investigations and to a jury during court proceedings.…”

“…Photography also is one of the most influential and significant mediums in helping to assist in the analysis of criminal cases. Due to their quickness and ease of understanding, digital photographs also present a practical and beneficial medium for communication [2]. The information contained in the digital evidence proved to be very helpful in documenting the crime scene and was used to reconstruct crimes for investigation [3].…”

“…The sophistication of digital mediums such as DSLR Cameras [7], CCTV [8], Drone [9], Mobile phones [10] that are becoming more and more accessible and easy to use makes image recording increasingly crucial for the criminal investigation. Digital photography has become essential in various fields, primarily in criminal investigations [2], to collect images and video [11].…”
