Microscope Noise¶

Note

For this section of the guide, we will be disabling all other effects in order to clearly show each option.

Unless otherwise noted, the following configuration was used as a base for this demo:

EMConfig.EnableGaussianBlur = False
EMConfig.EnableInterferencePattern = False
EMConfig.BorderEdgeIntensity = 70
EMConfig.BorderThickness_um = 0.05

The Virtual Microscope supports a few configuration options regarding the addition of noise to generated images.

Parameter	Description
`GenerateImageNoise`	Enable or disable the generation of noise
`ImageNoiseIntensity`	Set the amount of noise to be generated, higher means more extreme noise
`PreBlurNoisePasses`	Number of iterations to generate noise prior to blurring images
`PostBlurNoisePasses`	Number of iterations to generate noise after blurring images

Example

GenerateImageNoiseImageNoiseIntensityPreBlurNoisePassesPostBlurNoisePasses

Enable or disable the generation of image noise.

Setting GenerateImageNoise to False results in the following image:

Default Render Example

EMConfig.GenerateImageNoise = False

Likewise, setting it to True will result in the following image: Default Render Example

EMConfig.ImageNoiseIntensity = 80
EMConfig.GenerateImageNoise = True

The image noise intensity value describes the amount of noise - higher numbers will indicate a more visible noise effect.

Setting it to 180 will result in the following image: Default Render Example

EMConfig.ImageNoiseIntensity = 180

Likewise, setting it to 100 will result in the following image: Default Render Example

EMConfig.ImageNoiseIntensity = 100

This sets the number of times to add noise prior to blurring the image.

Setting it to 1 will result in the following image: Default Render Example

EMConfig.PreBlurNoisePasses = 1

Likewise, setting it to 0 will result in the following image: Default Render Example

EMConfig.PreBlurNoisePasses = 0

Post blur passes specify how many times to add noise after the blurring step.

Setting it to 1 will result in the following image: Default Render Example

EMConfig.PostBlurNoisePasses = 1

Likewise, setting it to 2 will result in the following image: Default Render Example

EMConfig.PostBlurNoisePasses = 2
