I have this source code where I got it from net tutsplus. I have configured it and made it work in one PHP file. It does work by transferring the original image, but it does not generate to the thumbnails folder. <?php $final_width_of_image = 100; $path_to_image_directory = "../../img/events/" . urldecode($_GET['name']) . "/"; $path_to...
I came up with this: <?php $dir = $_GET['dir']; header('Content-type: image/jpeg'); $create = imagecreatetruecolor(150, 150); $img = imagecreatefromjpeg($dir); imagecopyresampled($create, $img, 0, 0, 0, 0, 150, 150, 150, 150); imagejpeg($create, null, 100); ?> It works by accessing: http://domain.com/image.php?dir=thisi...
Hey again... to those that may have read my previous question that got solved a couple minutes ago >.< The on-the-fly php script works perfectly, but when I went to upload new images into a gallery which I made myself, the images are resized to 150 x 150 for what I wanted... however, when it comes to new images being added it is all bla...
What is the best way to store images? Currently when an image is uploaded I resize it to 3 different sizes (a thumbnail, a normal size, and a large size). I save in a database a description of the image, the format, and use the id number from the database as the image name. Each size image has its own directory. Should I be storing the ...

I am saving an image bytes array as a thumbnail. The problem is that the transparent background color is black in my image.

Possible Duplicate: tracking an image in matlab Hi, I asked a similar question but wasn't quite clear before. I am trying to put a blue or an orange or some other colored circle (more like a donut) around a feature in an image so that I can track it. It should be more like a donut so that I can still view the image... Anyway, ...
I am investigating the possibility of image processing to identify certain objects and also count them in an image. I will be given a picture and I need to identify the number of boxes present in that image. Does anybody have any experience with any Machine Vision/ Image Processing libraries like ImageJ, Fiji, JAI, jMagick ,Java Visio...
Hi, I have resize images exceeding a max size. Methods I tried so far are not good enough :-( System.Drawing.Image.GetThumbnailImage generates very poor quality images in general. Playing with options like this one I can generate better images in quality but heavier than the original one. Probably the second option (or something ...
Hi everyone, I'm writing a little plugin for imageJ and I am drawing several regions as an overlay on the image. I'm using this code: ImagePlus imp = getImage(); Overlay ov = new Overlay(); for (int r=0; r<regions.length; r++) { ov.add(regions[r]); } imp.setOverlay(ov); Where regions is an array of Roi. This works as in...
I am doing a Final Year Project to track an object(human) by drawing a square around a human in a video. I am doing this project in C#.NET. I asked in a forum about this and they said to use GDI+ and mouse handling (which I have no clue about). Do I have to do segmentation and then identify the region where the square was drawn ? split...

Hello, We are now required by law to digitalize all the financial documents in our company and submit them to evaluations every 3 months. Since this is sensitive data we decided to take matters into our own hands and build some sort of digital data archiver. The tool works perfectly, but after 7 months of usage we are begining to worry...
I'm trying to find some info about removing an image background "automagically" if possible in .NET. Actually I could not find much data and I don't event know if it's possible or are there any API components available. Any ideas? ...
In an embedded C app, I have a large image that I'd like to rotate by 90 degrees. Currently I use the well-known simple algorithm to do this. However, this algorithm requires me to make another copy of the image. I'd like to avoid allocating memory for a copy, I'd rather rotate it in-place. Since the image isn't square, this is tricky...
I am currently working on an image processing demonstration in java (Applet). I am running into the problem where my arrays are too large and I am getting the "java.lang.OutOfMemoryError: Java heap space" error. The algorithm I run creates an NxD float array where: N is the number of pixel in the image and D is the coordinates of each ...
The unit of x-axis is hours (h), and there are 24 hours in total. The unit of y-axis is millions (m). How do I calculate the area under the red curve in the image in units of m*h? Important UPDATE Only the image is readily available (not the data), and I want to calculate the area programmatically. ...
Ok, I got a directory (for instance, named '/photos') in which there are different directories (like '/photos/wedding', '/photos/birthday', '/photos/graduation', etc...) which have .jpg files in them. Unfortunately, some of jpeg files are broken. I need to find a way how to determine, which files are broken. I found out, that there is t...
