AFAN: Augmented Feature Alignment Network for Cross-Domain Object Detection
نویسندگان
چکیده
Unsupervised domain adaptation for object detection is a challenging problem with many real-world applications. Unfortunately, it has received much less attention than supervised detection. Models that try to address this task tend suffer from shortage of annotated training samples. Moreover, existing methods feature alignments are not sufficient learn domain-invariant representations. To these limitations, we propose novel augmented alignment network (AFAN) which integrates intermediate image generation and domain-adversarial into unified framework. An generator proposed enhance by automatically generated soft labels. The synthetic images progressively bridge the divergence augment source data. A pyramid designed corresponding discriminator used align multi-scale convolutional features different semantic levels. Last but least, introduce region an instance proposals. Our approach significantly outperforms state-of-the-art on standard benchmarks both similar dissimilar adaptations. Further extensive experiments verify effectiveness each component demonstrate can

Cross-Domain Object Recognition Using Object Alignment
One popular solution to the problem of cross-domain object recognition is minimizing the difference between source and target distributions. Existing methods are devoted to minimizing that domain difference in a complex image space, which makes the problem hard to solve because of background influence. To discount the influence, we propose to minimize that difference using object alignment. We ...
متن کاملCross-Domain Weakly-Supervised Object Detection through Progressive Domain Adaptation
Can we detect common objects in a variety of image domains without instance-level annotations? In this paper, we present a framework for a novel task, cross-domain weakly supervised object detection, which addresses this question. For this paper, we have access to images with instance-level annotations in a source domain (e.g., natural image) and images with image-level annotations in a target ...
متن کاملPseudo Mask Augmented Object Detection
In this work, we present a novel and effective framework to facilitate object detection with the instance-level segmentation information that is only supervised by bounding box annotation. Starting from the joint object detection and instance segmentation network, we propose to recursively estimate the pseudo ground-truth object masks from the instance-level object segmentation network training...
متن کاملImage alignment via kernelized feature learning
Machine learning is an application of artificial intelligence that is able to automatically learn and improve from experience without being explicitly programmed. The primary assumption for most of the machine learning algorithms is that the training set (source domain) and the test set (target domain) follow from the same probability distribution. However, in most of the real-world application...
متن کاملUse of Generative Adversarial Network for Cross-Domain Change Detection
This paper addresses the problem of cross-domain change detection from a novel perspective of image-to-image translation. In general, change detection aims to identify interesting changes between a given query image and a reference image of the same scene taken at a different time. This problem becomes a challenging one when query and reference images involve different domains (e.g., time of th...
