Take pictures of all the tablets that are produced in the assembly line before they are sent to be packaged in containers. Use computer vision techniques on these pictures to separate the good tablets from the bad ones which prevent the bad tablets from getting shipped.
Take pictures of the containers containing all the packed tablets right before the containers are ready to be shipped. Then use computer vision techniques on these pictures to separate the good tablets from the bad ones.
Tell him to manually inspect each tablet produced and remove the deformed tablets from the production line.
Hire you to manually handpick each tablet and separate the bad ones from the good ones.

Answer: Take pictures of all the tablets that are produced in the assembly line before they are sent to be packaged in containers. Use computer vision techniques on these pictures to separate the good tablets from the bad ones which prevent the bad tablets from getting shipped.

Q2. In the video lecture, what methodology is presented to detect rust on iron bridges?
A person on the ground takes multiple high-resolution images from multiple places. A computer vision expert splits these images into smaller groups. Each of the smaller images is passed to a custom classifier that can detect the presence of the metal structure.

A person on the ground takes multiple high-resolution images from multiple places. A computer vision expert splits these images into smaller groups. Each of the smaller images is passed to a custom classifier that can detect the presence of the metal structure versus other, non-metal structures. After this, the images are passed through another custom classifier that is trained to detect the presence of rust in images.
