WebJul 31, 2024 · In this blog, we will discuss Hit-or-Miss transformation. This is basically used for shape detection or finding particular patterns in the given image. The shape or pattern to match has to be provided via the structuring element. This transformation can be easily implemented using the erosion operation.
