Caught on camera: Using AI to combat street crime

According to the Overseas Security Advisory Council (OSAC) Malaysia 2020 Crime and Safety Report, communal crimes successful Malaysia see snatch thefts and residential oregon commercialized robberies.

More than 2000 snatch thefts oregon robberies were reported successful Malaysia successful 2019. The planetary pandemic and consequent question power orders crossed the state whitethorn person reduced thoroughfare crimes, but they're anticipated to summation again arsenic the federation progresses towards a post-pandemic era.

In an effort to curb these crimes, metropolis councilors, retailers, commercialized and residential absorption person ramped up the deployment of closed-circuit tv (CCTV) cameras crossed urban areas. Kuala Lumpur has astir 1900 CCTVs for postulation management, 100 astatine flash-flood hotspots, 270 astatine nationalist parks,130 astatine rivers, and 309 for information surveillance.

Netizens person regularly witnessed the horrors of snatch thefts oregon robberies captured by CCTVs, which often spell viral connected societal media. The perpetrators are often capable to evade apprehension owed to the delayed effect successful alerting authorities.

Researchers astatine Monash University Malaysia's School of Information Technology embarked connected a probe and improvement inaugural to alteration accepted CCTVs into an autonomously intelligent strategy to observe thoroughfare crimes successful existent time. The task is led by Dr. Vishnu Monn Baskaran and Ph.D. pupil Marcus Lim Jun Yi, and funded by the Ministry of Higher Education's Fundamental Research Grant Scheme.

The probe is motivated by the accelerated improvement of artificial quality and, successful particular, heavy neural web algorithms.

"There is simply a caller accidental to recognize a reliable astute video surveillance framework, coupled with important advancements successful high-performance computing technology," says Dr. Baskaran.

A three-stage process

Typically, determination are 3 stages successful a astute video surveillance platform.

Stage 1 involves having AI-based bundle to process unrecorded video surveillance images to observe weapons. In astir cases, municipality robberies would impact weapons specified arsenic guns. Automatically identifying the beingness of a limb from a surveillance camera successful existent clip would summation the software's reliability successful assessing a menace wrong a surveilled area.

Stage 2 involves formulating a narration betwixt the idiosyncratic wielding the limb and the limb itself for assertive enactment recognition. Most importantly, the archetypal and 2nd stages are executed autonomously utilizing AI-developed bundle with minimal manual intervention.

Stage 3 generates an alert that's relayed to aesculapian crews and instrumentality enforcement officers to dispatch them rapidly to supply assistance to the unfortunate and apprehend the perpetrator.

The value of a real-time alert and effect mechanics could re-envision however AI is utilized to fortify instrumentality enforcement and to further deter transgression activities.

The Monash University Malaysia squad has completed signifier 1 successful processing a astute surveillance strategy that tin accurately observe handguns from surveillance cameras successful existent time.

The squad initially focused connected automated handgun detection, fixed that crimes utilizing firearms are much prevalent globally, particularly successful the Americas and successful parts of Southeast Asia.

The outcomes of the research were published successful the Engineering Applications of Artificial Intelligence journal. The squad besides won a gold medal for the project, named the Monash Automatic Gun Detection System (MAGTS), astatine the 31st International Invention, Innovation and Technology Exhibition 2020 (ITEX 2020).

The researchers are present formulating an close human-to-weapon exemplary for classifying assertive quality actions, which represents the 2nd signifier successful realizing a astute video surveillance platform. They're besides fine-tuning the outcomes from signifier 1 of the probe to observe knives and machetes, which are much prevalent successful robberies carried retired successful Malaysia.

This probe could besides beryllium extended to see idiosyncratic re-identification (that is, spotting oregon tracking a idiosyncratic from 1 camera to another). Through idiosyncratic re-identification, the determination oregon question of a perpetrator tin beryllium translated into geographical coordinates. These are past relayed to aggregate notification modules and plotted connected a map, representing a unified urban/city alarm notification system. This, successful turn, could further complement efforts successful apprehending the instrumentality offender.

The probe is driven by the Government Transformation Programme (GTP) 1.0 report, which states: "Despite the improvements successful the country's transgression complaint and its continued downward trajectory, nationalist cognition of information is inactive a situation arsenic 52.8% of the rakyat [citizens] accidental they inactive bash not consciousness safe."

The authorities recognizes that information is paramount successful sustaining robust economical growth. As such, the projected outcomes of this probe found the cardinal components of an autonomous surveillance platform.

The level perchance expands instrumentality enforcement's omnipresence programme by substantially reducing effect clip astatine the constituent of theft identification. These improvements align with mentation 2.0 of the GTP to trim the transgression index, which is expected to amended nationalist cognition of municipality safety.

In addition, it's envisaged that machine-assisted investigation of quality actions successful existent clip volition supply further enactment for societal and technological domains specified arsenic forensic science, transgression deterrence, transgression investigation, aesculapian aid, and psychotherapy.

These solutions tin alteration the nation's superior into a astute and harmless metropolis successful enactment with Transformasi Nasional (TN50), frankincense paving the mode for vibrant economical and societal development.
