  Many plants become limp or droop through heat, loss of water, or disease.
This is also known as wilting. In this paper, we examine plant wilting caused
by bacterial infection. In particular, we want to design a metric for wilting
based on images acquired of the plant. A quantifiable wilting metric will be
useful in studying bacterial wilt and identifying resistance genes. Since there
is no standard way to estimate wilting, it is common to use ad hoc visual
scores. This is very subjective and requires expert knowledge of the plants and
the disease mechanism. Our solution consists of using various wilting metrics
acquired from RGB images of the plants. We also designed several experiments to
demonstrate that our metrics are effective at estimating wilting in plants.
