Color Examples¶

[1]:

from easycv import Image, Pipeline
from easycv.transforms import GrayScale, Sepia, FilterChannels, GammaCorrection, Negative, Cartoon, PhotoSketch, ColorTransfer, Colorize, ColorPick, Quantitization, Hue, Contrast, Brightness, Hsv

For this example we will load an image with random(). For more examples of image loading check Image examples.

[2]:

img = Image.random()

Gray Scale¶

To convert the image to grayscale we just need to apply the transform, for more information check the reference.

[3]:

img.apply(GrayScale())

Sepia¶

To convert the image to grayscale we just need to apply the transform, for more information check the reference.

[4]:

img.apply(Sepia())

[4]:

../../_images/examples_transforms_color_9_0.png

Filter Channels¶

To remove a channel we just need to apply the transform with a list of the channels to remove, for more information check the reference.

[5]:

img.apply(FilterChannels(channels=[1]))

Gamma Correction¶

To apply gamma correction we just need to apply the transform with a new gamma value, for more information check the reference.

[6]:

img.apply(GammaCorrection(gamma=3.0))

[6]:

../../_images/examples_transforms_color_15_0.png

[7]:

img.apply(GammaCorrection(gamma=0.5))

[7]:

../../_images/examples_transforms_color_16_0.png

Negative¶

To convert the image to negative we just need to apply the transform, for more information check the reference.

[8]:

img.apply(Negative())

[8]:

../../_images/examples_transforms_color_19_0.png

Cartoon¶

To make an image look like a Cartoon we just need to apply the transform, for more information check the reference.

[9]:

img.apply(Cartoon())

[9]:

../../_images/examples_transforms_color_22_0.png

Photo Sketch¶

To make an image look like a pencil sketch we just need to apply the transform, for more information check the reference.

[10]:

img.apply(PhotoSketch())

[10]:

../../_images/examples_transforms_color_25_0.png

Color Transfer¶

To transfer the colors from source to target we just need to apply the transform, for more information check the reference.

[11]:

src = Image("images/source.jpg")
src

[11]:

../../_images/examples_transforms_color_28_0.png

[12]:

img.apply(ColorTransfer(source=src))

[12]:

../../_images/examples_transforms_color_29_0.png

Color Pick¶

To pick the color from the desired point or rectangle we just need to apply the transform, for more information check the reference.

[13]:

img.apply(ColorPick(method="point"))

[13]:

{'color': [127, 116, 120]}

Colorize¶

To colorize an image apply the Colorize transform to a grayscale image, for more information check the reference.

[14]:

gray = img.apply(GrayScale())
gray

[14]:

../../_images/examples_transforms_color_35_0.png

[15]:

gray.apply(Colorize())

[15]:

../../_images/examples_transforms_color_36_0.png

Quantitization¶

To reduce the number of colors of an image apply the Quantitization with the number of colors, for more information check the reference.

[16]:

img.apply(Quantitization(clusters=8))

[16]:

../../_images/examples_transforms_color_39_0.png

Hue¶

To add hue to an image apply the Hue with the value to add, for more information check the reference.

[17]:

img.apply(Hue(value=10))

[17]:

../../_images/examples_transforms_color_42_0.png

Contrast¶

To add contrast to an image apply the Contrast with alpha value of contrast to add, for more information check the reference.

[18]:

img.apply(Contrast(alpha=1.4))

[18]:

../../_images/examples_transforms_color_45_0.png

Brightness¶

To add brightness to an image apply the Brightness brightness to add, for more information check the reference.

[19]:

img.apply(Brightness(beta=10))

[19]:

../../_images/examples_transforms_color_48_0.png

Hsv¶

To reduce the number of colors of an image apply the Quantitization with the number of colors, for more information check the reference.

[20]:

img.apply(Hsv())
