tf.raw_ops.ImageProjectiveTransformV2
Applies the given transform to each of the images.
tf.raw_ops.ImageProjectiveTransformV2( images, transforms, output_shape, interpolation, fill_mode='CONSTANT', name=None )
If one row of transforms
is [a0, a1, a2, b0, b1, b2, c0, c1]
, then it maps the output point (x, y)
to a transformed input point (x', y') = ((a0 x + a1 y + a2) / k, (b0 x + b1 y + b2) / k)
, where k = c0 x + c1 y + 1
. If the transformed point lays outside of the input image, the output pixel is set to 0.
Args | |
---|---|
images | A Tensor . Must be one of the following types: uint8 , int32 , int64 , half , float32 , float64 . 4-D with shape [batch, height, width, channels] . |
transforms | A Tensor of type float32 . 2-D Tensor, [batch, 8] or [1, 8] matrix, where each row corresponds to a 3 x 3 projective transformation matrix, with the last entry assumed to be 1. If there is one row, the same transformation will be applied to all images. |
output_shape | A Tensor of type int32 . 1-D Tensor [new_height, new_width]. |
interpolation | A string . Interpolation method, "NEAREST" or "BILINEAR". |
fill_mode | An optional string . Defaults to "CONSTANT" . Fill mode, "REFLECT", "WRAP", or "CONSTANT". |
name | A name for the operation (optional). |
Returns | |
---|---|
A Tensor . Has the same type as images . |
