Block Category: Detection
Input Image Requirements: None
Description: The Back Projection block records how well the pixels of a specified image fit the distribution of pixels in a histogram model. That is, you calculate the histogram model of a specific feature (for example, flowers in a vase) and then use it to find that feature in a larger image (for example, a room with a table on which a vase is sitting).
When the image is read into Back Projection, it is automatically converted to gray scale.
