While 3D GANs have recently demonstrated the high-quality synthesis of multi-view consistent images and 3D shapes, they are mainly restricted to photo-realistic human portraits. This paper aims to extend 3D GANs to a different, but meaningful visual form: artistic portrait drawings. However, extending existing 3D GANs to drawings is challenging due to the inevitable geometric ambiguity present in drawings. To tackle this, we present Dr.3D, a novel adaptation approach that adapts an existing 3D GAN to artistic drawings. Dr.3D is equipped with three novel components to handle the geometric ambiguity: a deformation-aware 3D synthesis network, an alternating adaptation of pose estimation and image synthesis, and geometric priors. Experiments show that our approach can successfully adapt 3D GANs to drawings and enable multi-view consistent semantic editing of drawings.

提出了一个新颖的框架，以逐步收集基于标志的图形存储器，并使用收集的内存进行图像目标导航。给定目标图像搜索，具体的机器人利用语义内存在未知环境中找到目标。 ％从RGB-D摄像机的全景观察中收集语义图存储器，而无需知道机器人的姿势。在本文中，我们提出了一个拓扑语义图存储（TSGM），该记忆由（1）一个图形构建器组成，该图将观察到的RGB-D图像构造拓扑语义图，（2）横图搅拌器模块，该模块采用该模块收集的节点以获取上下文信息，以及（3）将上下文内存作为输入的内存解码器，以找到对目标的操作。在图像目标导航的任务上，TSGM明显优于成功率的竞争基线，而SPL上的竞争性基线的表现为 +5.0-9.0％，这意味着TSGM可以找到有效的路径。此外，我们在现实世界图像目标方案中在移动机器人上演示了我们的方法。

深度学习可以大大提高高光谱成像（HSI）的分类精度。尽管如此，对大多数小型高光谱数据集的培训并不是微不足道的。两个关键的挑战是录音的大信道维度以及不同制造商的摄像机之间的不兼容。通过引入合适的模型偏置并连续定义通道维度，我们提出了针对高光谱成像的这些挑战进行优化的2D卷积。我们根据两个不同的高光谱应用（内联检查和遥感）评估该方法。除了显示模型的优势外，修改还增加了其他解释能力。此外，该模型以数据驱动的方式学习了必要的摄像机过滤器。基于这些相机过滤器，可以设计一个最佳摄像头。

我们呈现Fouriermask，它采用傅立叶系列与隐式的神经表示结合起来，以产生实例分段掩模。我们将傅里叶映射（FM）应用于坐标位置，并利用映射特征作为隐式表示的输入（基于坐标的多层Perceptron（MLP））。 FouriMASK学习为特定实例预测FM的系数，因此将FM适应特定对象。这允许Fouriermask广泛化以预测来自自然图像的实例分段掩模。由于隐式功能在输入坐标的域中是连续的，因此我们说明通过对输入像素坐标进行分采样，因此我们可以在推理期间生成更高的分辨率掩码。此外，我们在Fourimask的不确定预测上培训渲染器MLP（Fourrierrend），并说明它显着提高了面具的质量。与在相同输出分辨率的基线掩模R-CNN相比，Fourimask在MS Coco DataSet上显示竞争结果，并在更高分辨率上超越它。

车辆可见光通信（V-VLC）是一种有前途的智能运输系统（ITS）技术，用于车辆到车辆（V2V）和基础设施（V2I）通信，利用发光二极管（LED）。 V-VLC系统性能的主要劣化因子是噪声。与传统的射频（RF）为基础的系统不同，V-VLC系统包括许多噪声源：太阳辐射，车辆，街道，停车车库和隧道灯的背景照明。传统的V-VLC系统噪声建模基于射击和热噪声形式的添加剂白色高斯噪声假设。在本文中，为了研究V-VLC信道的时间相关和白噪声分量，我们提出了基于Allan方差（AVAR）的噪声分析，该分析提供了一个时间序列分析方法来识别数据的噪声。我们还提出了一种基于广义的维纳流程的V-VLC信道噪声合成方法，以产生不同的噪声分量。我们进一步提出了一种基于卷积的自动化器（CAE）的去噪方案，以减少V-VLC信号噪声，分别实现0.0442和0.0474的重建根均方误差（RMSE），用于室内和室外通道。

隐式神经表示（INR）使用多层的感知来代表低维问题域中的高频函数。最近，这些表示在与复杂的3D对象和场景相关的任务上实现了最先进的结果。核心问题是高度详细信号的表示，其使用具有周期性激活功能（警报器）的网络来解决或将傅立叶映射应用于输入。这项工作分析了两种方法之间的连接，并表明傅里叶映射的Perceptron在结构上像一个隐藏层警报器。此外，我们确定先前提出的傅里叶映射与一般D维傅里叶系列之间的关系，导致整数晶格映射。此外，我们修改了渐进式培训策略，以便在任意傅里叶映射上工作，并表明它提高了插值任务的泛化。最后，我们比较图像回归和新颖观看综合任务的不同映射。我们确认前面发现映射性能的主要贡献者是其元素的嵌入和标准偏差的大小。

The 3D-aware image synthesis focuses on conserving spatial consistency besides generating high-resolution images with fine details. Recently, Neural Radiance Field (NeRF) has been introduced for synthesizing novel views with low computational cost and superior performance. While several works investigate a generative NeRF and show remarkable achievement, they cannot handle conditional and continuous feature manipulation in the generation procedure. In this work, we introduce a novel model, called Class-Continuous Conditional Generative NeRF ($\text{C}^{3}$G-NeRF), which can synthesize conditionally manipulated photorealistic 3D-consistent images by projecting conditional features to the generator and the discriminator. The proposed $\text{C}^{3}$G-NeRF is evaluated with three image datasets, AFHQ, CelebA, and Cars. As a result, our model shows strong 3D-consistency with fine details and smooth interpolation in conditional feature manipulation. For instance, $\text{C}^{3}$G-NeRF exhibits a Fr\'echet Inception Distance (FID) of 7.64 in 3D-aware face image synthesis with a $\text{128}^{2}$ resolution. Additionally, we provide FIDs of generated 3D-aware images of each class of the datasets as it is possible to synthesize class-conditional images with $\text{C}^{3}$G-NeRF.

In both terrestrial and marine ecology, physical tagging is a frequently used method to study population dynamics and behavior. However, such tagging techniques are increasingly being replaced by individual re-identification using image analysis. This paper introduces a contrastive learning-based model for identifying individuals. The model uses the first parts of the Inception v3 network, supported by a projection head, and we use contrastive learning to find similar or dissimilar image pairs from a collection of uniform photographs. We apply this technique for corkwing wrasse, Symphodus melops, an ecologically and commercially important fish species. Photos are taken during repeated catches of the same individuals from a wild population, where the intervals between individual sightings might range from a few days to several years. Our model achieves a one-shot accuracy of 0.35, a 5-shot accuracy of 0.56, and a 100-shot accuracy of 0.88, on our dataset.

Feature selection helps reduce data acquisition costs in ML, but the standard approach is to train models with static feature subsets. Here, we consider the dynamic feature selection (DFS) problem where a model sequentially queries features based on the presently available information. DFS is often addressed with reinforcement learning (RL), but we explore a simpler approach of greedily selecting features based on their conditional mutual information. This method is theoretically appealing but requires oracle access to the data distribution, so we develop a learning approach based on amortized optimization. The proposed method is shown to recover the greedy policy when trained to optimality and outperforms numerous existing feature selection methods in our experiments, thus validating it as a simple but powerful approach for this problem.

The purpose of this work was to tackle practical issues which arise when using a tendon-driven robotic manipulator with a long, passive, flexible proximal section in medical applications. A separable robot which overcomes difficulties in actuation and sterilization is introduced, in which the body containing the electronics is reusable and the remainder is disposable. A control input which resolves the redundancy in the kinematics and a physical interpretation of this redundancy are provided. The effect of a static change in the proximal section angle on bending angle error was explored under four testing conditions for a sinusoidal input. Bending angle error increased for increasing proximal section angle for all testing conditions with an average error reduction of 41.48% for retension, 4.28% for hysteresis, and 52.35% for re-tension + hysteresis compensation relative to the baseline case. Two major sources of error in tracking the bending angle were identified: time delay from hysteresis and DC offset from the proximal section angle. Examination of these error sources revealed that the simple hysteresis compensation was most effective for removing time delay and re-tension compensation for removing DC offset, which was the primary source of increasing error. The re-tension compensation was also tested for dynamic changes in the proximal section and reduced error in the final configuration of the tip by 89.14% relative to the baseline case.
