Photo Background Remover

A simple Go program that captures a photo from your webcam and removes the background.

go run main.go

The program will:
- Capture a photo from your webcam
- Remove the background
- Save both images in the output/ directory

Output

output/photo_TIMESTAMP.jpg - Original photo
output/photo_TIMESTAMP_nobg.png - Photo with background removed
