Computes a 3-D convolution given 5-D input
and filter
tensors.
tf.compat.v1.nn.conv3d( input, filter=None, strides=None, padding=None, data_format='NDHWC', dilations=[1, 1, 1, 1, 1], name=None, filters=None )
In signal processing, cross-correlation is a measure of similarity of two waveforms as a function of a time-lag applied to one of them. This is also known as a sliding dot product or sliding inner-product.
Our Conv3D implements a form of cross-correlation.
Args | |
---|---|
input | A Tensor . Must be one of the following types: half , bfloat16 , float32 , float64 . Shape [batch, in_depth, in_height, in_width, in_channels] . |
filter | A Tensor . Must have the same type as input . Shape [filter_depth, filter_height, filter_width, in_channels, out_channels] . in_channels must match between input and filter . |
strides | A list of ints that has length >= 5 . 1-D tensor of length 5. The stride of the sliding window for each dimension of input . Must have strides[0] = strides[4] = 1 . |
padding | A string from: "SAME", "VALID" . The type of padding algorithm to use. |
data_format | An optional string from: "NDHWC", "NCDHW" . Defaults to "NDHWC" . The data format of the input and output data. With the default format "NDHWC", the data is stored in the order of: [batch, in_depth, in_height, in_width, in_channels]. Alternatively, the format could be "NCDHW", the data storage order is: [batch, in_channels, in_depth, in_height, in_width]. |
dilations | An optional list of ints . Defaults to [1, 1, 1, 1, 1] . 1-D tensor of length 5. The dilation factor for each dimension of input . If set to k > 1, there will be k-1 skipped cells between each filter element on that dimension. The dimension order is determined by the value of data_format , see above for details. Dilations in the batch and depth dimensions must be 1. |
name | A name for the operation (optional). |
Returns | |
---|---|
A Tensor . Has the same type as input . |
