What I know about IMAGE Processing. Hough Transform For Hyperbola Detection - with known eccentricity. More Hough Transform examples! In last few examples, the Hough Transform are used to detect different shape, such as line and circle. For the circle detection, examples of circles with known radius detection and circles with unknown radius detection have been illustrated. Besides, different techniques of implemeting the code are shown, as in "for" loops and vectorized code. X-xo) 2/a 2 - (y-yo) 2/b 2 = 1.

What I know about IMAGE Processing. Welcome To A Simple Image Processing Blog. Welcome to a simple image processing blog, which has been here for 8 years. As mentioned by the title, this blog would talk anything about image processing via high level programming (not photoshop), mainly using the famous tools for this fields. I am in the process of collecting works from old time till now in this blog, trying to consolidates other blogs contents to single url in order to make the browsing easier.

What I know about IMAGE Processing. Character Recognition Example: An Explanation On the Simple Concept Used in This Demo. After I posted these series of examples, I’ve received a few comments from readers. Some of them using different version of software and can’t run the program successfully, some were happy with the simple code in which they had applied it to some other application, while a few readers were asking for more explanations on how these code work. The sub-images have to be cropped sharp to...

What I know about IMAGE Processing. Object Detection using Hough Transform (II). In previous post we've compare the Hough Matrix of a single dot, 2 dots and a single line. In this post, we'll look into more shapes:. For a square object, numbers of lines that cross 1 point, 2 points.until n points in which n is the lenght of the square (approximately) would be almost the same. This could be noticed in the right figure. Object Detection using Hough Transform (I). Hough Transform convert the binary image fr...

What I know about IMAGE Processing. Converting Pixels to Line. Converting pixels to line could be a complicated job. A simple example is shown to serve as the basis of a complicated problem. Clear all;clc;. I = imread('pic24.jpg');. I = im2bw(I);. 2 Finding all the pixels with the value of '1'. Y,x] = find(I= 1);. 3 Use the "polyfit" function to fit polynomial to data, in our case, since it is a straight line, we use 1st order polynomial or a linear equation Y = M*X C. P = polyfit(x,y,1);. Sz = size(I);.

What I know about IMAGE Processing. Detecting Objects' Shape(II) : Square Object. Detecting square object could be done in similar way we used to detect the round object. What we need to know is just the the formula for the area and the perimeter of a square object which is A = w 2 and P = 4*w. 1 Original image and the negative image (value 0 represent background. While 1 represent oject). S = imread('pic10.jpg');. S = im2bw(S);. 2 Labeling the objects in the image. The advance programming language.

What I know about IMAGE Processing. Measuring Object Length (with a Reference Object). It has been a long long time I've not update this blog due to my new notebook modem spoiled just after I bought it! The support staff came 3 times and now I am waiting for a replacement model. Further more, life become more and more busy, and sometimes I really out of idea what to post here. :P. Until I receive some e-mail from some reader. Let's see this simple example:. 1 Reading image and show the true color image.
