dc.description.abstract | Most women face violence in public and at home, including rape, physical and emo tional abuse, mocking, and harassment. A social violence support system might
allow people to seek aid from their friends, or relatives, or even request administra tive assistance. The goal here is to detect clearly and reliably the screams of the
individual in the position that is in any danger, that is, if the scream arose out of
dread and horror, based on a particular collection of audios. Screams elicited by
dread and panic usually have a shorter length, a higher frequency, and shrill pitches,
whereas screams elicited by other emotions or intentionally have a longer duration,
a fixed frequency, and pitch. In this sense, if we can use scream recognition to
recognize dangerous and consequential circumstances in our society and inform the
appropriate individuals at the appropriate moment, we will be able to avert these
issues to a degree that will benefit both society and its citizens. To assist the wider
populace, we have implemented a system using Convolutional Neural Network to
identify screams automatically. This model will assist us in recognizing screams
and sending SOS signals or messages to suitable contacts. As a result, people who
are in danger will be able to call the people from their selected contacts or general
authorities who are within their reach at any time. This system will not only assist
victims in avoiding danger, but it will also provide them with a sense of security.
On the other hand, the general authority will be able to use this software to limit
the quantity of social and domestic violence. | en_US |
