Cascade is a classic yet powerful architecture that has boosted performance on various tasks. However, how to introduce cascade instance segmentation remains an open question. A simple combination of R-CNN and Mask only brings limited gain. In exploring more effective approach, we find the key successful fully leverage reciprocal relationship between detection segmentation. this work, propose new framework, Hybrid Task (HTC), which differs in two important aspects: (1) instead performing...
Region anchors are the cornerstone of modern object detection techniques. State-of-the-art detectors mostly rely on a dense anchoring scheme, where sampled uniformly over spatial domain with predefined set scales and aspect ratios. In this paper, we revisit foundational stage. Our study shows that it can be done much more effectively efficiently. Specifically, present an alternative named Guided Anchoring, which leverages semantic features to guide anchoring. The proposed method jointly...
Feature upsampling is a key operation in number of modern convolutional network architectures, e.g. feature pyramids. Its design critical for dense prediction tasks such as object detection and semantic/instance segmentation. In this work, we propose Content-Aware ReAssembly FEatures (CARAFE), universal, lightweight highly effective operator to fulfill goal. CARAFE has several appealing properties: (1) Large field view. Unlike previous works (e.g. bilinear interpolation) that only exploit...
Graphene's unique electronic and optical properties have made it an attractive material for developing ultrafast short-wave infrared (SWIR) photodetectors. However, the performance of graphene SWIR photodetectors has been limited by low absorption as well ultrashort lifetime photoinduced carriers. Here, we present two mechanisms to overcome these shortages demonstrate a graphene-based photodetector with high responsivity fast photoresponse. In particular, vertical built-in field is employed...
Instance segmentation has witnessed a remarkable progress on class-balanced benchmarks. However, they fail to perform as accurately in real-world scenarios, where the category distribution of objects naturally comes with long tail. Instances head classes dominate long-tailed dataset and serve negative samples tail categories. The overwhelming gradients lead biased learning process for classifiers. Consequently, categories are more likely be misclassified backgrounds or To tackle this...
Microring resonators, due to their ability enable robust strong light–matter interactions within structures, have garnered substantial interest for utility in sensing applications, particularly the realm of gas detection. However, there is an inherent trade-off between a microring resonator's quality factor and confinement air, making it difficult balance them. Here, we demonstrate novel solution with suspended nanomembrane silicon (SNS) resonator. This resonator has ultrathin sub-wavelength...
