fast-skimage 0.2.0

Fast and easy image processing using an Image class based on the scikit-image, numpy and matplotlib libraries.

fast-skimage

Welcome to fast-skimage, an image acquisition and processing library. This powerful library offers a wide range of tools for advanced image manipulation and analysis, wrapped up in the accessible Image class.

Features

• Advanced Manipulation: Apply complex operations like adding watermarks, noise detection, auto-enhancement, and saturation increase with simple method calls.

• Filtering and Thresholding: Includes mean, median filtering, Otsu's thresholding, and custom thresholding methods for image segmentation and noise reduction.

• Fourier Transforms: Utilize Fourier-based methods for reducing image dithering and other artifacts.

• Histogram Operations: Equalize and stretch image histograms to improve contrast and visibility.

• Texture Analysis: Perform texture segmentation using a variety of descriptors.

• Small Image Library: 7 various pictures for testing are provided with the package (see section "Image Library" below).

Getting Started

1. Installation: Clone the repository or download the Image class module to your project.

2. Dependencies: Ensure all dependencies such as numpy, matplotlib, scikit-image, and PyWavelets are installed.

3. Usage: Import the Image class from the module and instantiate it with the path to your image or a NumPy array.

Example

from fast_skimage import Image

from fast_skimage import etretat

from skimage.data import immunohistochemistry



img = Image("Pictures/camera.jpg")  # Load an image with path...

img2 = Image(immunohistochemistry())  # ... or numpy array ...

colored_image_array = etretat() # ... or a library image.

img3 = Image(colored_image_array.get())



img2.auto_enhance()  # Apply auto-enhancement

img3.auto_enhance()



img3.show(subplots=(1, 2, 1), size=12)  # Display the result

img2.show(subplots=(1, 2, 2), title='Immunochemistry Image')



img.show(size=(12, 6), type_of_plot='hist', axis=True)  # Plot histogram

Image Library

A small image library is provided along with the Image class. These can be manually extracted with the following lines:

from fast_skimage import image_name

image_array = image_name()

image = Image(image_array.get())
