Bad Pixel Replacement (BPR)

Overview

Designed methods to detect and replace defective pixels in image sensors.

Responsibilities

• Identified dead, hot, and stuck pixels
• Developed interpolation-based correction methods
• Integrated real-time correction strategies

Approach

• Threshold-based detection
• Neighborhood interpolation
• Adaptive replacement strategies
