Installing OpenCV 3.0 and Python 3.4  on Windows
I recently decided to update to the newest OpenCV version (3.0) and wanted to add Python 3.4+ along with it. It took me a couple hours to set up because I couldnât find a good tutorial on how to install them on Windows. So, hereâs my attempt at a tutorial based on what I have just been through. Hope it helps.
For the rest of this post, I will showâŚ

How to use Twitter as a scientist
How to use Twitter as a scientist #HEMBAD
if you are a scientist, with âjoining Twitterâ and then âdoing stuff with Twitterâ on your To Do list, you might feel a little intimidated by the long list of possible people to follow. Moreover, following @CNN and @BarackObama might be the first thing you do, and might be suggested to you, but these are not your main sources of scientific joy and information.
So letâs take this step by step.âŚ

CUDA Random Numbers
CUDA Random Example
In order to use cuRAND, we need to add two include files into our program:
#include <curand.h> #include <curand_kernel.h>
cuRAND uses a curandState_t type to keep track of the state of the random sequence. The normal C rand function also has a state, but it is global, and hidden from the programmer. This makesrand not thread-safe, but easier to use.

Bilateral Filtering
Popular Filters
When smoothing or blurring images (the most popular goal of smoothing is to reduce noise), we can use diverse linear filters, because linear filters are easy to achieve, and are kind of fast, the most used ones are Homogeneous filter, Gaussian filter, Median filter, et al.
When performing a linear filter, we do nothing but output pixelâs value g(i,j) which is determined as aâŚ

OpenCV: Color-spaces and splitting channels
Conversion between color-spaces
Our goal here is to visualize each of the three channels of these color-spaces: RGB, HSV, YCrCb and Lab. In general, none of them are absolute color-spaces and the last three (HSV, YCrCb and Lab) are ways of encoding RGB information. Our images will be read in BGR (Blue-Green-Red), because of OpenCV defaults. For each of these color-spaces there is a mappingâŚ

Design considerations
OpenCV GPU module is written using CUDA, therefore it benefits from the CUDA ecosystem. There is a large community, conferences, publications, many tools and libraries developed such as NVIDIA NPP, CUFFT, Thrust.
The GPU module is designed as host API extension. This design provides the user an explicit control on how data is moved between CPU and GPU memory. Although theâŚ
