Introduction

Content-Based Image Retrieval (CBIR) should be the right title for this article. CBIR is a way to index or find a similarity between images in a multimedia database. There are methods such as Fourier Transform, Hough Transform, Wavelet Transform, Gabor Transform, Hadamard transform coefficients to be used as engine in CBIR system. Retrieval by image content has received great attention in the last decades. Several techniques have been proposed to the problem of finding or indexing images based on their contents. Each method used has strong and weak points.

In this article I try to give an overview view about CBIR because this kind of topics is the most frequently asked question in Digital Image Processing. Here I used CxImage library from Davide Pizzolato (http://www.aoi.it). The latest version of CxImage library contain a function to transform an image into it's frequency domain that is FFT2 function. The technique I used here is not really efficient but at least this article will guide you to more advanced CBIR.

If you want more efficient method try to follow this links http://debut.cis.nctu.edu.tw/pages/slides/jeffrey/present2.pdf and http://www.telecom.tuc.gr/paperdb/icassp99/PDF/AUTHOR/IC991221.PDF

Finding Similiar Images

There are 4 steps to perform image retrieval based on the similarity:

  1. Load Query Image (Image we want to search for or find images similar to this) 
  2. Generate Signature of Key Image using Fourier Transform 
  3. For every images in the database Load and generate the signature 
  4. Calculate Euclidean Distance for Key Image Signature and Database Image Signature 
  5. Put the value in a auto-sorted listbox to make similarity investigation easier because smallest value stay in the top of the list and step down for similar images.

The image similarity depend on Euclidean Distance. The smaller the distance the image will get more similar. In measuring similarity, there are few famous math formulas such as Dice similarity coefficients, Jackard, Otsuka, Simpson, Manhattan, Robinson, and more.

The libraries used:

  1. CxImage (http://www.aoi.it)
  2. CTokenEx Written by Daniel Madden (daniel.madden@compaq.com)
  3. CDirDialog (I forgot the creator)
