<---------WEBCAM MOTION DETECTOR---------->

DESCRIPTION

A PROGRAM THAT DETECTS MOVING OBJECTS IN THE DESKTOP VIDEO FRAME AND RECORDS THE TIME OF THE OBJECT ENTERING OR LEAVING THE WEBCAM FRAME SIMULTANEOUSLY A GRAPH WITH BE PLOTTED SHOWING THE RECORDED TIME OF THE MOVING OBJECT APPLICATION IS MADE FROM SCRATCH WITH PYTHON USING ATOM

WORKING/BASE OF THE PROJECT

NOTE:- code is not explained here .it is in the file

The program will open the webcam and will capture or form multiple frames as follows:-

1. the first frame / background / first picture will be captured as soon as the webcam will open and stored it in a variable . this first frame will act as the base picture to detect the difference of the next frames formed . It will be static just used to compare other images
2. the base picture will be converted into a grey scale image
3. then an object/animal will appear , then convert this frame too into grey scale image
4. Now we have two grey scale images to check the object we will do the difference of both the grey scale image , known as the delta frame notice that behind the human u will see the lamp in the room , the python script is making the difference of the two grey scale images to check the moving object the picture is a grey scale image where every pixel of the image has it's own intensity value . the black area of the image shows there is no motion and in place of the object (human) there is high intensity showing there is alot of motion . some other white areas are seen that depicts the light in the room
5. THRESHOLD FRAME :- THIS IS TO FORM THE FINAL FRAME , the code says for this frame the convert into white where the value of the pixel is above 1000 (high intensity) to difference out the moving object . so you come up with the outline of the object/contours contours are the white patches in the frame . to remove the small contours along the object(biggest contour/human) we will write code that will remove the contours from the frame by setting the size ( if size == something , keep else remove )

then we will make a rectangle around the biggest contour / moving object .
