Dear Mahanthi,

in my case I would develop my own software which can be more suitable to the problem. However, I can refer you to the following two sites which sell software that analyzes object size, area, and volume in images.

SigmaScan

Imaris

Hi Mahanthi

i think you can work with MATLAB and use its image processing toolbox.

its easy to use and more codes you can find for your work.

Good luck

I used ImageJ not for  volume . It has lotz of plugins , you play around with it.

Dear Mahanthi;

Measuring volume of any object cant be performed unless you have a series of images taken from different sites. I recommend you to the stereo imaging topics to know the procedures normally used for this purpose.

Best Wishes

Dear Mahanthi, you can obtain the volume of any fruit through a simple method.

Inmerse their fruit, in water contained in a suitable graduated glass vessel and determine the water displaced volume. That you have a good day

I would definitely like to recommend MIPAR at www.MIPAR.us. It is very powerful and intuitive 2D/3D image analysis software about to be released as a free beta trial on December 14. It's been able to tackle segmentation problems few other software titles could.

CVIPtools will allow experimentation with many methods and parameters for you to develop an optimal algorithm. available here:
