New work problems

27 January 2013 - 08:11 AM

Hi All,


I'm Egyptian and currently working in Austria under a work permit which is restricted for 4 months, which is the length of the contract, if they are happy with me they will prolong it. I have just started the job 3 weeks ago, and was doing good some kind of electronic circuit design and embedded software. The direct manager was happy, and told me wow so fast for some task, and some very good words.


I had meeting with the ceo two days ago, and he told my how do you like the work ? I told him its good, I like the manager, the enviroment,..etc. Then he said you have to push your self more, you are just working by 70-80% percentage, I was shocked, and very sad by these words, he said also I know that you have a lot of knowledge, I also asked the direct manager to give you lots of work packages!!!


I'm really sad and that would affect my living in Austria and dont want to come back to Egypt ; (

Correlating between Cluster and Points

17 September 2012 - 03:34 PM

I'm clustering a set of points using DBScan algorithm. I have a set of IDs for a set of points and I have a set of clusters, where each cluster has a set of points. I would like to correlate between the clusters and the points ID.

For example I have a set of ids { 1,2,3,4}, Now if I have two cluster and two clusters has two points, then those two points of the first cluster should have the ids 1,2 and for the second one 3,4. Also If I have 4 clusters and each cluster has one point, then the Ids of the points should be 1,2,3, and 4. Furthermore, If I have two clusters but one cluster has 3 points and the other one has one point, then the Ids of the points should be 1,2,3 for the first cluster's points and for the second cluster's point is 4.

I tried to code it, but I'm stopped at calculating the formula to achieve that scenario.

// for each cluster
for( int j = 0; j<clusters.size();j++ )
// for each point in that cluster
for ( int i=0; i < clusters[j].m_Points.size(); i++)
// assign its ID from the _IDs array based and save it in Clusters Vector
clusters[j].m_IDs.push_back(_IDs[j+ i*clusters[j].m_Points.size()]);


Recommendation for Improving Programming Skills

15 September 2012 - 02:53 PM

Hi All,

I'm 25, I know C++ syntax since 9 years.. but It seems that I have copied so much code, and I didn't learn that much and didn't solve a lot of algorithms in my own. Currently I'm working for computer vision programmer as a junior and I have difficulity of doing algorithms like blob tracking or object tracking, writing algorithms like KNN, Quadtree,..etc.
I don't know what to do, or what to improve, I tried to write asteriods game, I have finished it, and here you can watch it

What should I do more to enhance my skills ?

OpenGL Coordinate System

Hi All,

How does Opengl coordinate system relate to texture coordinates ?
what does affect quad and texutre coordinates calculations from the point of initilizing opengl ?
