Processing of images of suspended particles in Matlab

Code and examples to process images for particle characterization. The code functionality is described in a manuscript currently submitted to Journal of Open Research Software.<br>UPDATE Feb. 15, 2016: The ParChar code has been updated so it now also searches for other image files than jpeg. The ParChar_run code had a few flaws that has been updated (e.g. it was saving to an incorrect location and looking for the wrong ParChar code).

用于颗粒表征的图像处理代码与示例。该代码的功能已在一篇已提交至《开放研究软件期刊》（Journal of Open Research Software）的手稿中进行了阐述。<br>2016年2月15日更新：ParChar代码已完成更新，如今可处理JPEG格式以外的其他图像文件。此前ParChar_run代码存在若干缺陷，现已完成修复（例如：原代码存在保存路径错误、检索ParChar代码时匹配路径有误等问题）。
