콘텐츠 소개

In present study, I developed a powerful Matlab-based software package,
imageProcAnal (Version 1.0), for image processing and analysis. Several modules
were available for uses. Functions to resize, crop, rotate, dilate, pixelate and
watermark images are included in Basic module. Adjustment of image edge,
contrast and gamma factor is available in Adjustment module. In Denoising
module, four elementary denoising methods and their joint uses are provided for
image filtering and denoising. In Edge and Contour Detection module, five methods
for detection of image edge and contour are provided. Also three methods for
image sharpening are available in Sharpening module. Segmentation module
includes three methods for image segmentation. Connected components recognition
can be made in Object Recognition module. In Analysis module, Pearson correlation
measure was provided to align images. Pearson correlations and p values among
images can be obtained. Mutiple methods across different modules can be
sequentially and jointly used to achieve ideal image. Finally, some examples for
image processing can be found in Demo module. In addition to conventional
methods, I proposed two new methods for image segmentation, i.e., TDOS
(Two-Dimensional Ordered Segmentation) and MWAS (Moving Windows Averaging
Segmentation). In TDOS, which is based on two-dimensional ordered cluster
analysis, the pixels belonging to the same segment (class) are adjoint and are not
separated by any of remaining segments. MWAS is based on moving windows
averaging method for transect boundary detection. Algorithms of TDOS and MWAS
were given, and full Matlab codes of MWAS were given.
