Ideation:
Started exploring Open CV (Computer Vision). It is one amazing utility! So what better way to learn, than implementing your ideas right!
So 1 use case that is fun and interesting that I could think of is a scenario where the user shows the application what all food ingredients he/she has, and the application should reverse engineer the items and present recipes.
So I have started exploring Open CV through a youtube channel :
https://www.youtube.com/channel/UC5hHNks012Ca2o_MPLRUuJw
The guy is brilliant, keeps things simple and to the point.
So far, I was able to :
> do some basic stuff, play around with camera of the system.
>Perspective projection was pretty cool
> selective masking of colors, displaying only the stuff I wanted
> Conceptually understood dilation (fill stuff in the masked region), erosion (remove stuff from the masked region), contour lines (draws boundaries around the objects of a given color - was pretty cool)
> On doing so, I came across something, which even I wanted to try out using the knowledge I had acquired.
>Realised, having a lot of sub ideas in your way of implementing your bigger idea is a good way to learn better!
>to implement Harry Potter's Invisibility Cloak! :)
> Concept was simple:
> Select your object of choice, that you would be using as a "Cloak".
> Record that bkg, wen the scene is empty (without you in the cam's field of view or the "Cloak":). Store it.
> During live, remove the Cloak obj(mask it) and select only the masked areas from the static background that you had recorded beforehand.
Looked something like this :
was excited! :)
>Went through a video where he uses algorithms SIFT, SURF and ORB to detect features in an image.
Apparently the above techniques for feature detection is only good for image comparisons itseems and not good for videos as it takes a good computational time.
> Am about to learn mouse tracking, once that is done, I want to be able to :
>Take area input from user - project it onto the screen
Take aways:
1. Main Idea: Show Me Recepies
2. Sub Ideas: Harry Potter Cloak (done), Input area - project it to screen
3. There are lot of things that I went thru - dont remember everything - the ones that I remember - Dialation, Erosion, Perspective Projection, Selective Masking (inRange), Contour Lines, Sift, Surf, Orb.....
4. Ofcourse, I dont need to remember anything at all, but just try and focus on the things that would cater my "idea". Hence its important to have an idea in mind wen u are learning something.
End.
