This class implements a layer that extracts a set of pixel sequences along the specified coordinates from a set of two-dimensional images.

Settings

There are no settings for this layer.

Trainable parameters

This layer has no trainable parameters.

Inputs

The layer has two inputs.

The first input accepts a blob of integer or float data with a set of two-dimensional images:

• BatchLength is equal to 1
• BatchWidth is the number of sequences in the set
• ListSize is equal to 1
• Height is the images' height
• Width is the images' width
• Depth is equal to 1
• Channels is the number of channels the image format uses

The second input accepts a blob with int data that contains lists of pixel coordinates, of the dimensions:

• BatchWidth is equal to the first input BatchWidth
• Channels is the length of each sequence
• all other dimensions are equal to 1

The coordinates of a pixel (col, row) are represented in this blob by a single integer number equal to row * GetImageWidth() + col.

Outputs

The single output returns a blob of the same data type as the first input with the pixel sequences:

• BatchLength is equal to 1
• BatchWidth equals the inputs' BatchWidth
• ListSize equals the second input ListSize
• Height, Width, and Depth are equal to 1
• Channels is equal to the first input Channels

The blob contains the pixel sequences taken from the images of the first input using the coordinates from the second input.
