Here we present some examples of the data collected. The dataset contains the images, fully supervsied masks, and center point annotations.
Full dataset contains 21,436 cranberry images of size 456x608. Images were collected using a Phanthon 4 drone from a smal range of altitutdes with manually fixed camera settings: 100 ISO, 1/240 shutter speed, and 5.0 F-Stop. Data was collected at weekly intervals to capture albedo variations in cranberries.
Annotation procedure include center points and berry-wise annotations. Center points locate cranberry centers with equal number of background points. Background points are annotated at random locations, as far as possible from nearby cranberry annotations. Berry wise annotations are fully supervsied labels tht account for cranberry occlusion. While only visible cranberries are labeled, if there is an occluded part, it is estimated.
CRAID has an average of 39.22 cranberries per image, with minimum count of 0 and maximum count of 167. A single image covers roughly 1 square foot area.
