This paper deals with the analysis of images of biological tissue that involves ring structures, such as tree trunks, bivalve seashells, or fish otoliths, with a view to automating the acquisition of age and growth data. A bottom-up template-based scheme extracts meaningful ridge and valley curve data using growth-adapted time-frequency filtering. Age and growth estimation is then stated as the...

We present a method for segmenting 2D microscopy images of freshwater green microalgae. Our approach is based on a specialized level set method, leading to efficient and highly accurate algae segmentation. The level set formulation of our problem allows us to generate an algae’s boundary curve as the result of an evolving level curve, based on computed background and algae regions in a given im...

On 9 March 2020, 2 days before the World Health Organization declared COVID-19 a global pandemic, two of authors (microbiologist and infectious diseases expert Associate Professor Siouxsie Wiles cartoonist Toby Morris) released their first output together: an animated GIF (Graphics Interchange Format) known as “Flatten Curve”. The graphic went viral on Twitter with over 10 million impressions i...

the quantitative analysis of cardiac motions in echocardiography images is a noteworthy issue in processing of these images. cardiac motions can be estimated by optical flow (of) computation in different regions of image which is based on the assumption that the intensity of a moving pattern remains constant in consecutive frames. however, in echocardiographic sequences this assumption may be v...

These notes are taken from a lecture series in three parts given at the University of Sydney in April 2006. In the rst part, we introduce Shimura curves for the non-expert, avoiding technicalities. In the other two sections, we discuss the moduli interpretation of Shimura curves and treat some of the computational aspects. Ever wondered what a Shimura curve is? They lie at the crossroads of man...

PURPOSE It is not yet possible to estimate the number of cases required for a beginner to become expert in laparoscopic radical prostatectomy. We estimated the learning curve of laparoscopic radical prostatectomy for positive surgical margins compared to a published learning curve for open radical prostatectomy. MATERIALS AND METHODS We reviewed records from 8,544 consecutive patients with pr...
