What is this?¶
Pick up bright pixels from an image and encode the indices.
The combination of this node and
jsk_perception/SparseImageDecoder provides almost the same function as image thresholding.
Note that this node is irrelevant to sparse coding or auto encoder.
Input image to encode.
If either width or height of the input image is greater than 256,
data32field is used.
If it is less than or equal to 256, then
data16field is used instead.
Maximum publishing rate [Hz].
Print number of encoded pixels as NODELET_INFO.
