Abstract

We introduce the notion of groupoid pre-equivalences and prove that they give rise to groupoid equivalences by taking certain quotients. Then, given an equivalence of Fell bundles $\mathscr{B}$ and $\mathscr{C}$ and another equivalence between $\mathscr{C}$ and $\mathscr{D}$, we construct an equivalence between $\mathscr{B}$ and $\mathscr{D}$ out of the tensor product bundle. As a consequence, we obtain that Fell bundle equivalence is indeed an equivalence relation., Comment: 42 pages

Abstract

Inspection is a vital part of quality control in manufacturing systems. Some edges are difficult to extract because of the brightness and contrast caused by lighting equipment. To solve this problem, an improved Faster R-CNN algorithm is proposed. Based on the original framework, the anchors are optimized by clustering and RoI Pooling is replaced by RoI Align to improve the detection capability of sand inclusion defects. Training and testing on the image dataset of engine surface, the algorithm is verified to give the type and location of the defects with high accuracy and efficiency.
