BUG: Image Processing Performance Degradation in adjust_brightness_contrast (frontend\src-tauri\src\services\mod.rs)

[priyankeshh]

Is there an existing issue for this?

• I have searched the existing issues

What happened?

The current implementation of adjust_brightness_contrast function shows several performance issues:

1. Memory Leaks:

• The image cache grows indefinitely without any size limits or cleanup mechanism
• Each cached image consumes memory until application restart
• No eviction policy for least used cached images

2. CPU Bottlenecks:

• The parallel processing implementation is incomplete
• Lookup table (LUT) calculation is inefficient
• Pixel manipulation code has redundant calculations

3. Cache Issues:

• Cache key generation is basic and could lead to collisions
• No cache invalidation strategy
• No cache size management

4. Performance Impact:

• High memory usage for large images
• Slower processing times for batch operations
• Potential application crashes with large image sets
