果蔬质量分级是农业产业成功营销的一项重要任务。有许多标准来确定水果和蔬菜的质量，其中体积和质量估计是重要的。当前的体积和质量估计方法在考虑农业中大量的水果和蔬菜时存在一些缺点。这些缺点是需要高效率的人力资源和长时间。对于新鲜水果和蔬菜来说，手工加工有时具有破坏性。基于图像分析的自动化和非破坏性技术可以在一定程度上缓解这个问题。基于计算机视觉的解决方案成为具有挑战性的不规则形状的水果和蔬菜从一个单一的视图图像。本文通过使用创新的拆分和合并技术来解决这些挑战。输入的图像已经通过了几个预处理阶段，以减少噪声，以及从背景中分割的对象。然后，分割的对象沿主轴沿着被分割为两个单独的对象。提取有效的边界点，并随后通过每个部分的多项式表达式近似。通过对多项式进行积分来提取体积。将各部分的体积相加，得到整个水果或蔬菜的体积。质量是通过使用密度、质量和体积关系计算的。
Fruit and vegetable quality grading is a major task for successful marketing in the agricultural industry. There are many criteria to determine the quality of fruits and vegetables out of which volume and mass estimation are important ones. The current processes of volume and mass estimation have some drawbacks while considered for a large number of fruits and vegetables in the agricultural industry. These drawbacks are the requirement of highly efficient manual resource and long time. The manual processing is sometimes destructive in nature for fresh fruits and vegetables. An automated and non-destructive technique based on image analysis may alleviate the problem to a certain extent. Computer vision-based solution became challenging for irregular shaped fruits and vegetables from a single view image. This paper addresses the challenges by using an innovative split and merge technique. The input image has been passed through a few pre-processing stages to reduce the noise as well as segment the object from the background. Then the segmented object has been split into two separate objects along the major axis. The valid boundary points are extracted and subsequently approximated by a polynomial expression for each part. The volume is extracted by integrating the polynomial. The volumes from the parts are summed to get the volume of entire fruit or vegetable. Mass is computed by using the density, mass and volume relationship.
