pyimkernel 0.6.1

Applying some image kernel(s) on a grayscale or color scale image

Pyimkernel

With this package, You can apply various image kernels such as Blur, Sobel, Scharr and so forth (The list of image kernels is mentioned below) on a grayscale or color scale image, and then show them. All of these happens using the "ApplyKernels" class to reach a wide range of effects and enhancements in digital images.

Installation

pip install pyimkernel

Usage

from pyimkernel import ApplyKernels
import mnist # pip install mnist
import cv2
import os

# Load data
X_train, X_test, y_train, y_test = mnist.train_images(), mnist.test_images(), mnist.train_labels(), mnist.test_labels()

# Create an instance
imkernel = ApplyKernels(random_seed=0)

# Grayscale
# Show image 9 
imkernel.imshow(X_train[19], cmap=plt.cm.gray)

# Apply blur kernel on a grayscale image 9
filtered_image = imkernel.apply_filter_on_gray_img(X_train[19], kernel_name='blur')

# Show the filtered image 9
imkernel.imshow(image=filtered_image, cmap='gray')

# Color Scale
# Read the flower image
image1 = cv2.imread(os.path.join('Images', '1.jpg'))

# Show the flower image
imkernel.imshow(image1.reshape(image1.shape[0], -1), cmap='gray', figsize=(20, 10))

# Show the filtered flower image
imkernel.imshow(image=imkernel.apply_filter_on_color_img(image1, kernel_name='laplacian', with_resize=True),
                figsize=(7, 6), cmap='gray')
