This paper presents a hardware architecture for calculating the city-block and chessboard distance transform on binary images. It is based on applying multiple morphological erosions and adding the result, enabling both processing pixels in raster scan order and a deterministic execution time. Which distance metric to be calculated is determined by the shape of the structuring element, i.e. diamon

The present study examined assertiveness and responsiveness in two different conversational contexts: children with specific language impairment (SLI) interacting with an age-matched peer with typical language development (TLD) and children with SLI interacting with a language-matched peer with TLD. The dialogues where the 10 participating children with SLI interacted with an age peer were charact
