This is the third video to my image recognition basics series. Image recognition can be used for all sorts of things like facial recognition, identifying what is in pictures, character recognition, and more.

can anyone please help me to get python code which can recognise sides of polygon….please please

ARNAB KUMAR DAS says:

sir can you show after processing images how to find the shortest path between two images….sir please sir give a video on this

Jeff Lee says:

This is a great video, I wanted to thank you and ask you a question. I am interested is it possible to take a picture of multiple objects and have it display the outline or silhouette of the items to the proper scale? I only need it in black and white, but am trying to figure out how to understand what the distortion and or parallax will be. I would think there is a method to ensure the proper scale of all items taking a photo and just getting the outline. If there is I would love to hear your thoughts.

Why we use the alpha in the array..

Sujith Palanivasagam says:

Thank you so much for the additional information! It really helped me understand the concept of RGB.
Keep up the good work!

Frederic Pool says:

This is very interesting!

Vanditha Rao says:

I have just 3 numbers in a row i.e. only RGB. For the image that I use, I don't have the alpha value. This is the output I got:

[[[255 255 255]
[255 255 255]
[255 255 255]
…,
[255 255 255]
[255 255 255]
[255 255 255]]

[[255 255 255]
[255 255 255]
[255 255 255]
…,
[255 255 255]
[255 255 255]
[255 255 255]]

[[255 255 255]
[255 255 255]
[255 255 255]
…,
[255 255 255]
[255 255 255]
[255 255 255]]

…,
[[255 255 255]
[255 255 255]
[255 255 255]
…,
[255 255 255]
[255 255 255]
[255 255 255]]

[[255 255 255]
[255 255 255]
[255 255 255]
…,
[255 255 255]
[255 255 255]
[255 255 255]]

[[255 255 255]
[255 255 255]
[255 255 255]
…,
[255 255 255]
[255 255 255]
[255 255 255]]]

Can somebody help me to understand? Can somebody tell me if the output is okay?

skip to 5:20 to skip his blabber about colors

Manpreet Singh says:

hey, your videos are really good and helpful , i am very curious to know about why you are not using some sort of machine learning algorithm for this problem ? i would like to join , if you are having some tutorial for ocr implementation using algoithms
.

Aljon Rosales says:

Hi there sentdex, about this image recognition, is it possible that I can connect it to a search engine?
thanks by the way

Anonymous Coward says:

in physics terms, photon emission from a surface uses RGB to affect the receptors in your eye vs. photon absorption (then reflection) on a surface uses RYB to affect the receptors in your eye

Yu Xue says:

Very good tutorial and friendly for beginners, though I am not a beginner, but also get a lot of help.

Jeru Luke says:

great stuff man

Deino475 says:

I get the joke. Matrix, because thats a Matrix. No… Never mind.

sentdex says:

@Eliecerecology Prrrroooobbably you forgot the parenthesis somewhere. Would need to see your code.

Eliecerecology says:

Hi Harrison,
I do not know what is going on, it appears:
<PIL.PngImagePlugin.PngImageFile instance at 0xb4435f6c>
