What technology is used to identify movie titles in poster images?

1. Facial recognition

2. Optical character recognition (OCR)

3. Object detection

4. Custom vision

The correct answer is: Optical character recognition (OCR)

Optical character recognition (OCR) is the technology that is specifically designed to recognize and interpret text within images. In the context of identifying movie titles in poster images, OCR analyzes the visual data, detects characters and words, and converts them into machine-readable text. OCR can effectively process different fonts, colors, and layouts typically found in movie posters, enabling it to extract title information accurately. This technology thrives on the representation of text in various formats, making it essential for tasks that involve recognizing and digitizing words from graphic content. When applied to movie posters, OCR can identify the title amidst other visual elements, leading to successful recognition of the content depicted in the poster images. Other technologies like facial recognition primarily focus on identifying human faces rather than reading text. Object detection identifies and classifies items within images, but does not specifically extract text. Custom vision, while useful in training models to recognize unique images, does not inherently target text recognition tasks as its primary function. Thus, OCR stands out as the appropriate answer for recognizing movie titles in poster images.
