QUESTION
I am doing my master thesis regarding floor based obstacle detection with a Time of Flight (ToF) camera.
I found out there are alot of applications that use the V- and U- Disparity map to detect and track objects and the ground plane with a stereo vision approach. They calculate the disparity with the two pictures taken and then create a Histogram of the values so in the V- Disparty map the ground plane is visible as slanted line and obstacles stand out from it. So my question is, if it is possible to generate the disparity map from the data from a time of flight camera? As far as i know those things give me back a point cloud (x,y,z coordinates from each pixel) and a amplitude image of the scene.
So the depth for the disparity in stereo vision is calculated like this:
depth = (baseline * focal length) / disparity)
A ToF camera has an objective and therefore it is using the pin hole approach to calculate the right depth. So is there any posibillity to gain a disparity map with an ToF camera?
Thanks in advance!
...ANSWER
Answered 2022-Apr-15 at 08:37TL;DR: No, you can't generate a disparity map from a time-of-flight camera.
I have not used many time-of-flight cameras, but the ones I have used have given me uint16 matrices. The shape of the matrices were X by Y with the uint16 values corresponding to the distance from the camera in millimeters. This is not a point cloud; it is a depth map.
Since there is only one camera, there is no disparity and thus no disparity map, but I think you know that.
To create a disparity map from the depth map, I assume you could just make up some fake distance between the cameras (baseline) and rearrange your equation from there. So it would be disparity = (fake_baseline * focal_length) / depth. From here you could calculate your U and V disparity maps like usual.
Since your baseline will be a made-up number, I have a hunch that this wouldn't be useful for ground plane detection nor object avoidance. Thus, I think you would be better off just using the depth map from the time-of-flight camera as-is.
I have not tried this before, nor ever used u-disparity maps before, so take my answer with a grain of salt (I could be wrong).
QUESTION
As part of my bachelor's thesis, I am trying to create a universal ontology for organizations (I know about the existence of The Organizational Ontology from the W3C). In the process, I came up with the following scheme (ontology drawn in pencil). The idea is to have one main entity (in my case it is the entity Workspace) for which I could set its type (organization, department, position, person, place) and which I could pair with itself (with using the typed relationship "Relation") to build any arbitrarily complex organizational structure.
I tried to translate the drawn ontology into an RDF graph using the WebVOWL online utility and this is what I got (picture of ontology).
Unfortunately, my knowledge of ontological modeling theory and semantic web technologies leaves much to be desired, and I ask people who understand them to help me.
Correct me if I'm wrong, but I have a feeling that in the ontology I've built, the Relation entity must have all the links at once. (Relation - relationType - HoldsPost, Relation - relationType - ReportsTo, Relation - relationType - subOrganization, etc.). I need the Relation entity instance to have only one relationship (For example, only Relation - relationType - HoldsPost).
Only one solution to this problem comes to mind - get rid of the HeadOf, HoldsPost, ReportsTo, .. nodes and instead add a string node in which to write the desired value, depending on the type of relationship.
So it seems that the problem is how to build an ontology that will provide a Relation instance with only one of the types listed, and not all at once.
I would be really grateful for any help and feedback.
Also I am attaching the contents of the Turtle file generated by the WebVOWL utility:

For some reason my code is not reproducing the table I wanted in the document. Only a bold line shows up but no cells or text. What am I doing wrong?
...ANSWER
Answered 2022-Apr-01 at 23:31That's not a bold line, that literarily is your table ... just scaled down sooooooo much by \resizebox
that you can't see it. That's one of the many reasons you should never use \resizebox
for elements which contain text. Other reasons are suboptimal choice of letter shapes and a ransom letter appearance to the final document with all the different font sizes.
Other problems:

l
columns for your table and then even wrapping the verrrrrrrrrrrry long lines into additional tables withc

Here is my code:
...ANSWER
Answered 2022-Mar-31 at 19:32Long numbers can't be broken across lines and your page only has so much available space. A couple of strategies to nevertheless fit your table on the page:
pay attention to significant figures. Given the values of the standard deviations, it makes little sense to give all your numbers with two decimal places
decrease the padding around the vertical line (or better, have a look at the booktabs user guide which shows how professional looking tables can look like (there is a library for tabularray, so the same layout can also be done with this package))
change the ration of the column width, e.g. with
X[1.3,valign=h,halign=l]
for the first columnuse a smaller font
make the margins smaller
use a bigger paper
I was already wondering this yesterday, but isn't it strange to have the 1-1 cell centred if the rest of the table is all left aligned?

QUESTION
For my master's thesis I have to work with a database in order to make a logistic regression model. One of the variables of my model is NEWS, This should be a dummy variable that is equal to 1 if a company had to publish a negative net income (bad news) in a given year, which belongs to the time period of this study (2017, 2018 and 2019), while it still had a positive net income the year before (good news). The dummy is equal to 0 otherwise. Now my professor said that I had to make a dummy that is equal to one when a company had a negative net income during one of the three years, O otherwise. That part I understand. But then she also said that I had to use a LAG function in order to find out if the company had a positive net income the year before the negative net income. And that part I don't understand. I don't really understand how i should do this with the help of SPSS. Below you can find a small part of the data I have to work with.

QUESTION
I've been trying ways to distill (a lot of) database index suggestions into a set of indexes that are applicable to most databases. To do that it turns out I need to solve a pretty basic but NP complete set theory problem: the minimum set cover problem.
This means that given a set of sets, select a subset of sets s
that covers a certain domain u
, but if u
isn't given make it the union of s
. The most optimal subset of sets is the one reaching a certain minimum, usually the minimal amount of sets, but it could also be a minimum in total weight if the sets are weighted.
ANSWER
Answered 2022-Mar-25 at 11:25Here's a Clojure version of the greedy set cover algorithm i.e. selects a set which covers the most uncovered elements at each iteration. Rather than use loop

QUESTION
I'm working on my bachelor thesis (on Computer Science) and right now I'm having a problem about finding shortest path between two points on 3D triangular mesh that is manifold. I already read about MMP, but which computes distance function $d(x)$ between given point and vertex $x$ on mesh.
I got to know that the problem I'm solving is named Geodesics but What I really couldn't find is some good algorithm which uses A* for finding shortest path between two given points on two given vertices.
I 'invented' also algorithm which uses A* by using Euclidian Distance Heuristics and correction after finding new Point on any Edge.. I also have edges saved in half-edge structure.
So my main idea is this:
- We will find closest edge by A* algorithm and find on this edge point with minimalizing function $f(x) + g(x)$ where $f$ is our current distance and $g$ is heuristics(euclidean distance)
- Everytime we find new edge, we will unfold current mesh and find closest path to our starting point
So now my questions:
- Do you know some research paper which talks about this problem ??
- Why nobody wrote about algorithm that uses A* ??
- What are your opinions about algorithm I proposed ?
ANSWER
Answered 2022-Mar-15 at 09:55I am no expert in the matter so read with prejudice. Also sorry this is more of a comment than answer...
First You should clarify some things:
- the mesh is convex or concave?
- are the path always on surface or can fly between faces on the outside (if concave) but never inside?
- are the start/end points on edges of faces or can be inside?
Assuming concave, points on edges and only surface paths...
I think the graph A* approach is unusable as there is infinite possible paths between point and any edge of the same face so how you test all of them?
If you really want A* then you can do something similar to raster A*
so resample all your edges to more points
so either
n
points or use some density like 10 points per average edge length or some detail size.use graph A* on resampled points (do not handle them as edges anymore)
However this will produce only close to shortest path so in order to improve the accuracy you should recursively resample the edges near used point with higher and higher density until the distance between resampled points get smaller than accuracy.
Another option would be using something similar to CCD (cyclic coordinate descent) so:
- create plane that goes through your 2 points and center of your mesh
- create path that goes through all intersection of plane and faces between the 2 points (use the shorter on from the 2 options)
- iterativelly move intersections back and forward and use greedy approach to get the result
However this might get stuck in local minima... You could use search/fitting approaches instead but those will get very slow with increasing number of faces
I got the feeling you might also do this using RANSAC ...
From my point of view I think the first A* approach is the most promising, you just need linked list of points per each edge and one cost counter per each its point from this you can simply encode even the recursive improvement of accuracy. It can be done even in-place so no reallocation needed in the recursion ... And also the algo is not complicated so you should have no problems implementing it, and the result is guaranteed which is not the case with other approaches I mention... Another pros is that it can be used even if start/endpoint does not belong to edge...
