ImageEffect

ImageEffect[image,"effect"]
applies the specified image effect to image.

ImageEffect[image,{"effect",params}]
uses parameters params.

DetailsDetails

• Artistic image effects:
•  {"Charcoal",x} charcoal sketch effect {"Comics",{t1,t2}} comics effect with thresholds t1 and t2 {"Embossing",x,α} embossing by an amount x at an angle α {"MotionBlur",d,α} motion blur of size d and angle α, given in radians {"OilPainting",x} artistic oil painting effect {"Posterization",n} posterization effect using n levels in each channel {"Solarization",t} solarization or Sabatier effect
• Color vision deficiencies:
•  "Deuteranopia" insensitivity to green, confusing green and red "Protanopia" insensitivity to red, confusing green and red "Tritanopia" insensitivity to blue, confusing blue and yellow
• Pseudo-random noise effects:
•  {"Noise",a} adds zero-mean uniform noise of amplitude a {"GaussianNoise",σ} adds zero-mean Gaussian noise with standard deviation σ {"PoissonNoise",a} adds an amount a of Poisson noise {"SaltPepperNoise",f} adds salt-and-pepper noise to a fraction f of the image
• Use {"SaltPepperNoise",{fs,fp}} to specify different salt and pepper fractions.
• In each case, "effect" can be used instead of {"effect",}, and uses default values for parameters.
• When using {"PoissonNoise",a}, the noise scale σ is defined as 100×(1-a)/a and each pixel value p is replaced with PoissonDistribution[p×σ]/σ.
• can be used to retrieve a list of all available image effects.
• ImageEffect returns a grayscale image for single-channel images. All other images are converted to RGB.
