segment image to features

How can I get the image feature vectors from a segmented image using MTLAB?

It totally depends on what features you want to measure. There are no generic "features" for an image. You have to say what you are interested in. Maybe it's the brightness or size of something in your image. Maybe it's the velocity of moving particles or the color of something. You forgot to attach your image and say what you'd like to measure.

If you have any more questions, then attach your data and code to read it in with the paperclip icon after you read this:

You didn't read the first link I gave you. How do I know? Because you didn't attach your image. Now you'll have to wait because I'm heading out for most of the rest of the day.

I'll check back at the end of the day probably.

By the way I don't know what "brightness index" is but the brightness of the image is defined by the value of all the pixels in the array.

given such and image matrix B as input, returns a feature vector

@Ahmad Alosta not sure what @Dumbledore's reply to you meant so I'll let him answer that.

To get the "ones" digit of an integer, you can do this:

v = randi(1000, 1, 30)

v = 1×30

490 839 723 905 492 631 134 384 493 104 78 555 485 83 237 645 679 678 432 931 669 13 867 90 266 183 416 183 712 307

onesDigit = mod(v, 10)

onesDigit = 1×30

0 9 3 5 2 1 4 4 3 4 8 5 5 3 7 5 9 8 2 1 9 3 7 0 6 3 6 3 2 7
