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…

Z values get rescaled while plotting in 3d
x_3d = 5.171875 , 5.3125 , 5.171875 ... 6
y_3d = 0, 1, 2, 3, 4, 5, .... 1500 (1500 points)
z_3d = -10.493983 , 22.128998 , -14.582531 , 34.687847 ,

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…

handling different mesh resolutions
So lets say we have a model that generates a 3d point cloud given some context information. The generative model is based on encoder/decoder architecture.
The model is typically trained on input size of 10000 points and outputs size of 2500 points.…

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…
