Agricultural food's logistics needs to be efficient and to provide assurance on the safety and quality of its products which consumers could trust. This paper designs a machine vision system by which fruits or vegetables can be detected for defects and damages during transportation and storage. The color histogram extracted in local image patch is used as image feature and the Linear SVM (Support...
External appearance is one of the most significant attributes for fruits when consumers decide to choose or reject them, thus packinghouses need to adopt appropriate systems that are capable of detecting the skin defects for fruits before packing them into batches and reaching the end consumers. For this purpose, this paper proposes a new method to detect fruit skin defects by using machine vision...
The original MeanShift algorithm uses color histogram as the target feature and does not take the objectives of spatial information into account. Therefore, there are some stability problems under the complex background. It leads to target losing easily. A new tracking algorithm named weighted mean of the centroids is proposed in the paper. In order to improve the robust of tracking process, the weighted...
