BackProjection
The BackProjection block records how well the pixels of a specified image fit the distribution of pixels in a histogram model.
Library
ComputerVision/Images/Detection
Description
This means that you calculate the histogram model of a specific feature (e. g. flowers in a vase) and then use it to find this feature in a larger image (for example, a room with a table on which a vase is sitting).
When the image is read into BackProjection, it is automatically converted to gray scale.
