Options
- Enable Image Filtering
- This globally enables/disables filtering images regardless
of other filter settings.
- Filter Probability
- Governs the odds that an image will be processed by a random filter.
When the slider is all the way to the left, images are always
filtered. When it is all the way to the right, images are
rarely filtered (1 out of every 100 images)
- Available Filters
- This list allowes individual filters to be enabled/disabled.
The Filters
- Add Noise
- Perform an arithmetic mean of the original image and an equal sized
image of random black and white values.
- Arithmetic
- Perform arithmetic mean of the original image and another random
image that has been resized to match the first.
- Beam Closing
- Performs a Dilate followed by and Erosion.
- Beam Opening
- Performs an Erosion followed by a Dilate.
- Blur
- Blurs the image with a nearest neighbor convolution with the following matrix:
1 2 1
2 1 2
1 2 1
- Dialate
- For each RGB channel, pixel values are set to the minum of their
nearest neighbors in a 3x3 matrix.
- Edge Detect
- Performs a nearest neighbor convolution with the following matrix:
2 2 2
2 -16 2
2 2 2
- Erosion
- For each RGB channel, pixel values are set to the
maximum of their nearest neighbors in a 3x3 matrix.
- Gray Posterize
- In HSV color space, pixels are fit within a range
of eight gray values based on their HSV value.
- Gray Scale
- Converts the entire image to gray scale using the equation:
Value = (Red * 0.2125) + (Green * 0.7154) + (Blue * 0.0721)
- Invert
- Inverts the RGB values of the image using
X' = (255 - X) OR 255
where X is the value of the individual RGB channel. There is
a random chance that the image will be converted to grayscale first.
- Rotate Hue
-
- In HSV color space, the image's hue is rotated 180°. Red is swapped
with cyan, magenta with green and blue with yellow.
- Sharpen
- Sharpens the image with a nearest neighbor convolution with the following matrix:
1 1 1
1 -9 1
1 1 1
- Saturate
- In HSV color space, the image's saturation is set to 100%.
- Threshold
- In HSV color space, pixels with a value less than 55% are set
to black while those greater than or equal to 55% are set to white.
- Wierd #1
- Another nearest neighbor convolution with the following matrix:
-2 2 -2
2 -2 2
-2 2 -2
- Wierd #2
- Yet another nearest neighbor convolution with the following matrix:
2 2 2
2 -15 2
2 2 2
