A Library for LTC1665/LTC1660
ATmega328p does not provide any Digital/Analog conversion channels (although the D/A conversion can be simulated by means of measuring the […]
Interfacing LIS3LV02DL Using SPI — II
In my last post, I described in detail how to hand solder LIS3LV02DL, an LGA packaged accelerometer chip. And here […]
4 Digit 7 Segment Display Using Arduino
I was inspired by Paul’s 7 segment display and decided to build one myself. He used 4 common cathode 7 […]
A Parallel Port Stepper Motor Driver With Discrete Components
Using PC’s parallel port is a convenient way to control a stepper motor. For unipolar stepper motors, up to two […]
A Simple Program for Finding Palindromic Prime Numbers
A palindromic prime (palprime) is a prime number that is also palindromic. So out of curiosity I wrote a simple […]
Image Blur Detection via Hough Transform — IV
In my previous three articles (1,2,3) I discussed how to use Canny edge detection and Hough transform to identify blur […]
Image Blur Detection via Hough Transform — III
I will continue where I left off in my previous post. After performing Hough transform, and extracted the longest sections […]
Image Blur Detection via Hough Transform — II
In my previous post, I briefly discussed the rationale behind automated blur detection in digital imagery and did an overview […]
Image Blur Detection via Hough Transform — I
It is often necessary to identify and classify images based on their clarities. For instance, it is desirable for an […]
C++ Recursive Directory Search Under Linux
I was trying to search for some code examples on how to do a recursive directory search under Linux using […]
Timing Methods in C++ Under Linux
Measuring the execution time for code sections can be done in multiple ways in C++. Except for the time resolution […]
Magick++ Missing Delegate Error
As I wrote last time, I did a clean Ubuntu 9.04 install on my main PC.
Canny Edge Detection Auto Thresholding
In the example I gave in “Interfacing IPP with Magick++“, I illustrated how to use Intel’s Integrated Performance Primitives (IPP) […]
C++ IDEs Under Linux
So far I have been mainly using KDevelop and Code::Blocks as my C++ development IDEs. Recently, I started using NetBeans […]
An Image Class Based On IPP
A couple of weeks ago, I wrote about how to interface Integrated Performance Primitives (IPP) with Magick++. While IPP offers […]
