MPSCNNNeuronExponential
SYNOPSIS
#import <MPSCNNNeuron.h>
Inherits MPSCNNNeuron.
Instance Methods
(nonnull instancetype) - initWithDevice:a:b:c:
(nonnull instancetype) - initWithDevice:
Additional Inherited Members
Detailed Description
This depends on Metal.framework. Specifies the Exponential neuron filter. For each pixel, applies the following function: f(x) = c ^ (a *
x + b).
The default value of a is 1.0f, the default value of b is 0.0f, and the the default value of c is -1.0f. If the value of c is set to the
default value of -1.0f, the base (c) is set to e.
Method Documentation
- (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device
Standard init with default properties per filter type
Parameters:
device The device that the filter will be used on. May not be NULL.
Returns:
A pointer to the newly initialized object. This will fail, returning nil if the device is not supported. Devices must be
MTLFeatureSet_iOS_GPUFamily2_v1 or later.
Reimplemented from MPSCNNNeuron.
- (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device(float) a(float) b(float) c
Initialize a Exponential neuron filter.
Parameters:
device The device the filter will run on.
a Filter property 'a'. See class discussion.
b Filter property 'b'. See class discussion.
c Filter property 'c'. See class discussion.
Returns:
A valid MPSCNNNeuronExponential object or nil, if failure.
