FOR YOUR AMUSEMENT AND POSSIBLY REFLECTION. I was working on some image processing algorithm, and i realized that most people dont know what digital images are(i know most of you do know what they are) so i decided to share this demonstration. there are multiple types of images but the most common are 8bit RGB and 8bit Grey-scale 8bit is the range of the channel which is from (0 to 255); The value. -RGB means that each pixel of the image is made of three channels and each channel represent one of the primary light color (Red Blue and Green) and with the combination of those 3 colors we can create any color (ex: R+B+G= whit , R+G= yellow and so on ) -Grey-scale is basically one channel from black to whit but this is how we see the image, the sees it as a big matrix of numbers in the first pictures you see a heatmap of an object than i zoomed on in the second picture until the value of each pixel would be visible (black = cold ; whit = hot) PS: I ignored Alpha channels, Image compression and all the other stuff.... because come on I cant talk about all that stuff in one facebook post.
