2023年1月21日 · 本文的目标是详细分析一个经典的基于landmark (文章后面有时也称之为控制点control point)的图像warping (扭曲/变形)算法: Thin Plate Spine (TPS). TPS被广泛的应用于各类的任务中, 尤其是生物形态中应用的更多: 人脸, 动物脸等等, TPS是cubic spline的2D泛化形态. 值得注意的是, 图像处理中常用的 仿射变换 (Affine Transformation), 可以理解成TPS的一个特殊的变种. 什么是图像扭曲/变形问题? [3] . 给定两张图片中一些相互对应的控制点 (landmark, 如图 绿色连 …

The Toyota Production System (TPS) is an integrated socio-technical system, developed by Toyota, that comprises its management philosophy and practices. The TPS is a management system [ 1 ] that organizes manufacturing and logistics for the automobile manufacturer, including interaction with suppliers and customers.

The Toyota Production System (TPS) House is a common visual tool used to describe the LEAN Business System and the five (5) Focal Points for its implementation. But what does it really mean? And how does it apply to your program efforts?

It is a Toyota-developed system that focuses on reducing waste, increasing productivity, and maintaining high-quality standards. This guide delves deeply into TPS, from its fundamental principles and underlying philosophy to the tools and techniques that drive its implementation.

薄板样条 函数 (TPS)是一种很常见的插值方法。 因为它一般都是基于2D插值，所以经常用在在图像配准中。 在两张图像中找出N个匹配点，应用TPS可以将这N个点形变到对应位置，同时给出了整个空间的形变 (插值)。 2. 实现. import numpy as np. import random. import torch. from torchvision.transforms import ToTensor, ToPILImage. 产生波浪型文字. :param img: :return: ''' . h, w = img.shape[0:2] . N = 5 . pad_pix = 50 . points = [] .

与FOMM和MRAA采用局部仿射变换（local affine transformation）不同，TPSM采用TPS变换将源图像变换到驱动图像. TPS变换：给出两张图像的关键点keypoints，可以用最小的扭曲distortion把一张图片的关键点和另一张的对应上的变换

2022年3月27日 · Firstly, we propose thin-plate spline motion estimation to produce a more flexible optical flow, which warps the feature maps of the source image to the feature domain of the driving image. Secondly, in order to restore the missing regions more realistically, we leverage multi-resolution occlusion masks to achieve more effective feature fusion.

PS: The paper trains the model for 100 epochs for a fair comparison. You can use more data and train for more epochs to get better performance. Integrated into Huggingface Spaces 🤗 using Gradio. Try out the Web Demo: We support python3. (Recommended version is Python 3.9). To install the dependencies run:

2022年7月24日 · 本文提出无监督TPS Motion取得SOTA，1、提出thin-plate spline（TPS）运动估计，以生成更灵活光流，将源图特征迁移至目标图特征；2、为了补全缺失区域，使用多分辨率遮挡mask进行有效特征融合。

In summary, Toyota Production System is a model on how to achieve both customers and employees satisfaction, through respect and teamwork, on a basis of mutual trust between management and employees. Since late 80’s many companies around the world have implemented their version of TPS, called Lean manufacturing , which later evolved into Lean ...
