PointCloud value prediction - regression

I have point clouds for 400 objects. I have also some other features of these objects. For example their weights. How I can now train model to predict the weight based on the shape(point cloud)? I have seen pointnet but is seems it is only for…

3D point reconstruction from 2D images

I know this must exist, but I'm having enormous trouble finding the right search terms. Say I have a bunch of labelled 3D points, and I capture multiple 2D images of it. If I want to reconstruct the 3D points, are there well-established…

Interpreting the RGB or HEX value from a description of the color using NLP

We do have models that predict the basic color from its description, by basic color I mean red, blue, black etc. But I would like to develop a model that can spit out the RGB or HEX colors by a description of it, an example being, "yellow that is…

What is "Laplacian image space"?

I have been working through Beyond Face Rotation: Global and Local Perception GAN for Photorealistic and Identity Preserving Frontal View Synthesis where the authors make the following claim (subjection 2.2.1): ...the Laplacian space is more robust…

How to extract data from 3d model to a data table that is easy to read for machine learning algorithm?

I want to do something similar to Point Cloud. What I am NOT trying to do is to recognize objects or reconstruct them. I have a 3d file and I want to somehow read the data to use it in machine learning algorithm. Where to look for info? Googling…

Automating 3D Modeling using NLP

I would like to know if there is any way we can automate 3D modeling processes. Like if I give the model a text input such as "create a sphere and give it a red color" and the we need to get the model. To be precise, I would like to create a bot…

How to input a 3d model into ML algorithm?

I have a machine learning model that uses csv with measured data about buildings: width, length, height etc. I use it to predict some features and it works properly. I would like to drop csv with length, height and width, and I would like to use…

How can I input a 3D model into a neural net, and receive an edited 3D model out?

So for acoustic simulation, geometric complexity means that the process can take a long time. By reducing geometric complexity, the perceptual effect can be minimal, whilst reducing precomputation time. I want to automate this process, and I believe…

A small free dataset for 3D reconstruction from 2D images

I am trying to start coding on 3D image reconstruction from 2D images (so to map images to a 3D point cloud). Can any one please introduce a small free dataset to start with? I know BlendedMVS. But its 27 GB for its row resolution images. Does any…

Modelling a 3-variable system, with separate relations between two pairs

I am having some trouble approaching some data modelling of the following structured dataset I'm trying to analyse, and then creating a surface from it. So I have 3 variables: say x, y, and z (variable names changed for simplicity), where y is…

estimating coordinate correction

I'm working with 3d coordinate data (x,y,z), however I know that the z coordinate is systematically wrong and the error of z is dependant on both x and y. I however do have some data where I know the correct z value so I want to make a model that…
