• images are array of pixels that are represented in RGB values
• ball tracking alg that records the color of the center most pixel of a ball and then scans the entire image (every frame) to find the closest matched pixel.
• small regions of pixels are called patches.
• shows alg that detects edges in a gray scale image. the alg applies the following filter/kernel to every pixel in an image
  1 0 1
  1 0 1
  1 0 1
  
  contains the values for a pixel wise multiplication. The sum of which is stores in the centermost pixel.
  the 224 pixel becomes 147

applying a kernel to a patch of pixels is called a convolution
there are many different types of kernels: ones the find horizontal edges, vertical edges, sharpen images, blurs images, match certain shapes, finding lines...
kernels can become more comples and be good at finding noses, eyes in images.
These were the basis of early face detection algorithms (Viola-Jones alg)

today convolutional neural networks are used. this is a deep learning technique
I got lost following from this point on.
once you recognize a face determining things like if eyes are open or close, smiling or not are easier to determine bc it is just calculating the distance between two points. with this you can determine the mood of a person.

masters degrees in computer vision

also have a good chunk of ML/AI in them. so it is a bit flexible in that sense.

scholarships

how to find them?
contacting individual financial aid offices of each uni.

unis that caught my attention

residencies

there are residency programs that some companies offer. where they pay to train you.
typically last 6 months.
is this available for non-US citizens?
