Image registration is a common problem in computer vision, and speci cally in biomedical applications that require inter or intra modality image alignment. We have developed an ImageJ plugin called bUnwarpJ, which elastically registers pairs of images. This simple and easy-to-use plugin can be used by researchers and clinicians to create anatomical atlases, segment images using atlases, align p...

BACKGROUND Structured illumination microscopy has been extensively used in biological imaging due to its low cost and easy implementation. However, the lack of quantitative imaging capability limits its application in absolute irradiance measurements. METHOD We have developed a quantitative structured illumination microscopy image processing algorithm (QSIM) as a plugin for the widely used Im...

OBJECTIVE To verify the efficacy of ImageJ 1.43 n in determining the extent of apoptosis which is a complex and multistep process. STUDY DESIGN Cisplatin in different concentrations was used to induce apoptosis in cultured Hep2 cells. Cell viability assay and nuclear image analysis of stained Hep2 cells were used to discriminate apoptotic cells and cells suspected to be undergoing apoptosis f...

Purpose: Measurement error when determining the size of an angle is always an issue for clinicians. Computer assistance may help to decrease that error. The purpose of this study is to determine the amount of error when measuring Q-angles using a goniometer and the IMAGEJ program, a public domain program developed at the U.S. National Institutes of Health. Methods: Two investigators participate...
