下图显示了 PointMLP 在 modelNet40 上与其他网络的速度 / 准确率比较。PointMLP 的架构非常简单，与传统的点云网络类似， PointMLP 也采用了阶段结构，每一阶段（stage）通过最远点下采样以减少计算量。下图展示了 PointMLP 任意一阶段的操作。给定输入点云，PointMLP 使用残差点 MLP 块逐步提取局部特征。在每个...
在PointMLP中,常用的特征表示方法有以下几种: -坐标表示:直接使用点的坐标作为特征。 -法线表示:通过计算点的法线方向并进行编码。 -网络特征表示:使用预训练的深度学习网络提取点云特征。 2.3 MLP网络 MLP网络是一种典型的前馈神经网络,由多个全连接层组成。在PointMLP中,MLP网络被用于学习点云的特征表示和任务的...

Typically, PointMLP is used for classification tasks, where it is designed to find decision boundaries and establish a decision plane to categorise data within a dataset. The output represents the class of the object which is a qualitative value. However, the goal of this study is to identify...
PointMLP的关键的操作可以表述为: 其中,Φpre(·)和Φpos(·)为残差MLP块,这俩都是共享权重的多层感知机,其中前者从局部区域中提取特征,后者从聚合之后的特征里面提取更深层次的特征。其中,映射函数可以写成一系列结构一致的残差MLP块,MLP (x) +x,其中mlp由线性层、归一化层和激活层(重复两次)组合而成。 将...

we propose an MLP-Transformer hybrid module, which significantly enhances the model's convergence speed. Furthermore, to boost the feature representation capability of point tokens, we refine the classification head, enabling point tokens to directly participate in prediction. Experimental results on mult...
In this paper, we present DualMLP, a novel 3D model that introduces the idea of a two-stream network for existing 3D models to handle the trade-off between the number of points and the computational overhead. Existing works on point clouds use a small subset of points sampled from the en...
