Automatic Error Detection in Integrated Circuits Image Segmentation: A Data-driven Approach

no code implementations8 Nov 2022 Zhikang Zhang, Bruno Machado Trindade, Michael Green, Zifan Yu, Christopher Pawlowicz, Fengbo Ren

Due to the complicated nanoscale structures of current integrated circuits(IC) builds and low error tolerance of IC image segmentation tasks, most existing automated IC image segmentation approaches require human experts for visual inspection to ensure correctness, which is one of the major bottlenecks in large-scale industrial applications.

Object Detection on Single Monocular Images through Canonical Correlation Analysis

no code implementations13 Feb 2020 Zifan Yu, Suya You

In this report, we propose a two-dimensional CCA(canonical correlation analysis) framework to fuse monocular images and corresponding predicted depth images for basic computer vision tasks like image classification and object detection.
