Claim One:
1. A method of detecting and identifying a boundary of a field, comprising: defining positional coordinates of a seed point in a particular field, and a first bounding box around the seed point; obtaining a plurality of images over time that include the first bounding box around the seed point; clipping the plurality of images so that pixels in each image in the plurality of images refer to positional coordinates of the first bounding box; building a mask for a boundary of the particular field by identifying one or more edges of the particular field from the plurality of images; filling an area around the seed point and within the mask that has pixels of a similar color to pixels representing the seed point in each image in the plurality of images; checking the filled area around the seed point by a) defining a second boundary box for the filled area, b) determining whether threshold parameter values representing upper and lower distances from a pixel brightness of the seed point are satisfied in the second boundary box for the filled area, and c) tuning the threshold parameters values where the pixel brightness is outside the threshold parameter values to adjust the filled area; combining, for each image, the filled area into a combined flooded set; computing a boundary around the combined flooded set; and translating the boundary in the combined flooded set to positional coordinates in the particular field.
