phovision 0.1.0

A pure Python computer vision library

Phovision

A pure Python computer vision library implementing various image processing algorithms from scratch. This library provides implementations of common image processing operations without depending on other image processing libraries.

Features

Currently implemented algorithms:

• Gaussian Blur
• Median Filter (Noise Removal)
• Mean Filter (Averaging)
• Bilateral Filter (Edge-preserving smoothing)

Installation

pip install .

Usage

import numpy as np
from phovision.filters import gaussian_blur, median_filter, mean_filter, bilateral_filter

# Load your image as a numpy array
# image should be in grayscale or RGB format with values in range [0, 255]

# Apply Gaussian Blur
blurred = gaussian_blur(image, kernel_size=5, sigma=1.0)

# Apply Median Filter
denoised = median_filter(image, kernel_size=3)

# Apply Mean Filter
averaged = mean_filter(image, kernel_size=3)

# Apply Bilateral Filter
smoothed = bilateral_filter(image, kernel_size=5, sigma_spatial=1.0, sigma_intensity=50.0)

Requirements

• Python >= 3.7
• NumPy >= 1.21.0
