Generate print-ready images of a random speckle pattern for DIC applications.
#### Installation
This package is hosted on PyPI. Install it using `pip`:
```pip install speckle_pattern```
#### Example speckle pattern
```python
from speckle_pattern import generate_and_save
image_height = 50 # mm
image_width = 100 # mm
speckle_diameter = 3 # mm
dpi = 200
save_path = 'example.jpg'
generate_and_save(image_height, image_width, dpi, speckle_diameter, save_path)
```
<p align='center'><img src='example.jpg' width=400 alt='random speckle'/></p>
#### More speckle generation options
```python
from speckle_pattern import generate_and_save
image_height = 50 # mm
image_width = 100 # mm
speckle_diameter = 7.5 # mm
dpi = 150
save_path = 'example2.tiff'
size_randomness = 0.9 # set higher for more speckle size variety
position_randomness = 2.5 # set higher for more speckle position variety
speckle_blur = 0. # sigma of smothing Gaussian kernel
grid_step = 2. # approximate grid step, in terms of speckle diameter `D`
generate_and_save(
image_height,
image_width,
dpi,
speckle_diameter,
save_path,
size_randomness=size_randomness,
position_randomness=position_randomness,
speckle_blur=speckle_blur,
grid_step=grid_step,
)
```
<p align='center'><img src='example2.jpg' width=400 alt='random speckle 2'/></p>
#### Example line pattern
```python
from speckle_pattern import generate_lines
image_height = 50 # mm
image_width = 100 # mm
line_width = 5 # mm
orientation = 'vertical'
dpi = 200
save_path = f'example_lines_{orientation}.jpg'
generate_lines(image_height, image_width, dpi, line_width, save_path)
```
<p align='center'><img src='example_lines_vertical.jpg' width=400 alt='vertical lines'/></p>
#### Example checkerboard pattern
```python
from speckle_pattern import generate_checkerboard
image_height = 50 # mm
image_width = 100 # mm
line_width = 4 # mm
dpi = 200
save_path = f'example_checkerboard.jpg'
generate_checkerboard(image_height, image_width, dpi, line_width=line_width, path=save_path)
```
<p align='center'><img src='example_checkerboard.jpg' width=400 alt='checkerboard'/></p>
