# Image Style Processor
A comprehensive Python script that applies artistic hand-drawn and futuristic effects to images.
## Requirements
- Python 3
- OpenCV (cv2)
- NumPy
Install dependencies:
```bash
pip install opencv-python numpy
```
## Usage
```bash
python3 image_style_processor.py <input_directory> <output_directory> <style>
```
### Arguments
- `input_directory`: Directory containing your input images (PNG, JPG, JPEG)
- `output_directory`: Directory where processed images will be saved (created if doesn't exist)
- `style`: The artistic style to apply (see below)
## Available Styles
### Sketch Styles
1. **pencil_sketch** - Dense cross-hatching with progressive layers in shadows
- Best for: Detailed technical drawings, architectural scenes
- Features: Clean line art, 5 layers of cross-hatching, strong shadow definition
2. **ink_drawing** - Bold black outlines with comic book aesthetic
- Best for: Graphic novel style, high contrast scenes
- Features: Bold outlines, posterized tones, minimal shading
3. **charcoal_pastel** - Dramatic contrasts with soft, smudged textures
- Best for: Portraits, dramatic landscapes
- Features: Soft blending, grainy texture, highlighted areas
4. **conte_crayon** - Directional strokes following image contours
- Best for: Figure studies, natural forms
- Features: Stroke direction follows gradients, cross-hatching in dark areas
5. **gesture_sketch** - Loose, quick observational sketch style
- Best for: Quick studies, energetic compositions
- Features: Randomized line wobble, sparse suggestion lines
### Futuristic Styles
6. **circuit_board** - Tech blueprint with circuit paths and geometric patterns
- Best for: Sci-fi imagery, technological themes
- Features: Multi-layer circuit paths, connection nodes, technical grid overlay
7. **glitch_art** - Digital corruption with scan line shifts and pixel sorting
- Best for: Cyberpunk aesthetics, digital art
- Features: Horizontal scan artifacts, block displacement, pixel sorting, noise strips
8. **wireframe_topo** - Topographic contour lines with holographic grid
- Best for: Landscape, abstract patterns, sci-fi hologram effect
- Features: 20 contour levels, scan lines, measurement markers, grid overlay
9. **data_mosaic** - Voronoi geometric fragmentation with angular cells
- Best for: Abstract art, geometric compositions
- Features: 200 Voronoi cells, posterized tones, embedded geometric patterns
10. **holographic_scan** - CRT/hologram display with scanlines and HUD elements
- Best for: Retro-futuristic, heads-up display aesthetic
- Features: Scanlines, interference patterns, glitch effects, corner brackets, crosshair
## Examples
### Sketch Effects
Process images with pencil sketch:
```bash
python3 image_style_processor.py ./photos ./output pencil_sketch
```
Apply ink drawing style:
```bash
python3 image_style_processor.py ./input ./sketches ink_drawing
```
Create charcoal effect:
```bash
python3 image_style_processor.py ./images ./results charcoal_pastel
```
### Futuristic Effects
Apply circuit board style:
```bash
python3 image_style_processor.py ./photos ./output circuit_board
```
Create glitch art:
```bash
python3 image_style_processor.py ./input ./glitched glitch_art
```
Apply holographic effect:
```bash
python3 image_style_processor.py ./images ./holo holographic_scan
```
## Output
- Processed images are saved to the output directory with **the same filename** as the input
- Supported input formats: PNG, JPG, JPEG (case-insensitive)
- Output format: PNG (preserves quality)
- Original images are never modified
## Style Comparison
### Sketch Styles
- **pencil_sketch**: Most detailed, traditional drawing look
- **ink_drawing**: Boldest, most graphic/comic-like
- **charcoal_pastel**: Softest, most artistic/painterly
- **conte_crayon**: Most directional, follows contours
- **gesture_sketch**: Loosest, most expressive
### Futuristic Styles
- **circuit_board**: Cleanest, most technical/blueprint-like
- **glitch_art**: Most chaotic, digital corruption aesthetic
- **wireframe_topo**: Most structured, topographic/hologram feel
- **data_mosaic**: Most geometric, fragmented cells
- **holographic_scan**: Most retro-futuristic, HUD/CRT display
## Tips
- Images are automatically converted to grayscale before processing
- All styles work best with high-resolution images (300+ DPI recommended)
- Processing time varies by style:
- Fast: ink_drawing, glitch_art, holographic_scan
- Medium: charcoal_pastel, gesture_sketch, circuit_board, wireframe_topo
- Slow: pencil_sketch, conte_crayon, data_mosaic (due to intensive computation)
- For batch processing large collections, consider processing in smaller batches
- Randomized styles (glitch_art, gesture_sketch, data_mosaic) will produce slightly different results each run
## Technical Notes
### Randomization
Some styles use randomization for natural variation:
- **glitch_art**: Random scan line shifts, block positions
- **gesture_sketch**: Random line wobble, stroke placement
- **data_mosaic**: Random Voronoi cell centers
- **circuit_board**: Random pattern placement in dark regions
- **holographic_scan**: Random glitch line positions
### Processing Details
- **pencil_sketch**: Uses 5-level progressive cross-hatching algorithm
- **conte_crayon**: Follows Sobel gradients for directional strokes
- **wireframe_topo**: Generates 20 brightness-based contour levels
- **data_mosaic**: Creates 200 Voronoi cells via nearest-neighbor algorithm
- **holographic_scan**: Applies scanline patterns and interference waves
## License
Free to use and modify for any purpose.
