tfio.experimental.filter.gabor(
input, freq, sigma=None, theta=0, nstds=3, offset=0, mode=None,
constant_values=None, name=None
)
Args |
input
|
A 4-D ([N, H, W, C] ) Tensor.
|
freq
|
A float Tensor. Spatial frequency of the harmonic function.
Specified in pixels.
|
sigma
|
A scalar or 1-D [sx, sy] Tensor. Standard deviation in
in x- and y-directions. These directions apply to the kernel
before rotation. If theta = pi/2, then the kernel is rotated
90 degrees so that sigma_x controls the vertical direction.
If scalar, then sigma will be broadcasted to 1-D [sx, sy] .
|
nstd
|
A scalar Tensor. The linear size of the kernel is nstds
standard deviations, 3 by default.
|
offset
|
A scalar Tensor. Phase offset of harmonic function in radians.
|
mode
|
A string . One of "CONSTANT", "REFLECT", or "SYMMETRIC"
(case-insensitive). Default "CONSTANT".
|
constant_values
|
A scalar , the pad value to use in "CONSTANT"
padding mode. Must be same type as input. Default 0.
|
name
|
A name for the operation (optional).
|
Returns |
A 4-D ([N, H, W, C] ) Tensor.
