This class implements a layer that creates a set of two-dimensional images using a set of pixel sequences with specified coordinates.

Settings

Resulting image height

void SetImageHeight( int newHeight );

Sets the height of the output images.

Resulting image width

void SetImageWidth( int newWidth );

Sets the width of the output images.

Trainable parameters

The layer has no trainable parameters.

Inputs

The layer has two inputs.

The first accepts a blob with pixel sequences, of the dimensions:

• BatchLength is equal to 1
• BatchWidth is the number of sequences in the set
• ListSize is the length of each sequence
• Height, Width, and Depth are equal to 1
• Channels is the number of channels the pixels sequences (and the output images) use.

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

• BatchWidth equals first input BatchWidth
• Channels equals first input ListSize
• the other dimensions equal 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 dimensions:

• BatchLength equals 1
• BatchWidth equals inputs' BatchWidth
• ListSize equals 1
• Height equals GetImageHeight()
• Width equals GetImageWidth()
• Depth equals 1
• Channels equals the first input Channels

The blob contains the set of images with the pixel sequences written into the specified coordinates. The pixels that were not given are filled with zeros.
