Question
Match each computer vision model with its capability.
Capability:
- Overlaying traffic images with “mask” layers for highlighting various vehicles with specific colors.
- Categorizing data points based on whether they represent a vehicle (bus, taxi, etc.) or a cyclist.
- Reading road signs on a street.
- Finding people based on specific features.
Computer vision model:
- Optical character recognition (OCR)
- Face detection, analysis, and recognition
- Semantic segmentation
- Image classification
Answer
The correct matching is:
- Optical character recognition (OCR) – Reading road signs on a street.
- Face detection, analysis, and recognition – Finding people based on specific features.
- Semantic segmentation– Overlaying traffic images with “mask” layers for highlighting various vehicles with specific colors.
- Image classification – Categorizing data points based on whether they represent a vehicle (bus, taxi, etc.) or a cyclist.
Explanation
OCR technology specializes in recognizing and extracting text from images. Road signs primarily convey information through text, making OCR an ideal solution for decoding the message displayed on them.
Face detection, analysis, and recognition involves multiple steps:
- Face detection: Locates human faces within an image or video.
- Face analysis: Extracts features such as eyes, nose, and mouth and their relative positions.
- Face recognition: Compares the extracted features against a database of known individuals to identify them. This allows searching for people based on specific features such as glasses, hairstyle, or facial structure.
Semantic segmentation aims to divide an image into different regions based on their content. In this case, it would segment the traffic image in the following ways:
- Vehicles: One “mask” would be created to highlight all areas containing vehicles, regardless of their specific color.
- Specific colors: Additional “masks” could be created to identify vehicles of specific colors by further segmenting the “vehicle” region based on color information.
Image classification focuses on assigning an overall category to an entire image based on its dominant content. One such task is to classify the image into one of several categories that represent different types of vehicles.
