👉 A floodlet is a type of image processing algorithm used to detect and highlight features that are commonly found in images, such as valleys or depressions. Floodlets are typically defined by their smoothness and can be visualized using tools like an Image Processing Toolbox function called "Flood." These algorithms help identify areas with low detail or noise in the original image, making them useful for tasks such as edge detection, contour extraction, and object recognition.
