A Scanbox user requested to add the ability to display a histogram of image values in real-time. Here, I use a the general mechanism of memory mapped files in Scanbox to show how easy is to add such “plug-ins” to provide additional functionality to the system. The Matlab code necessary to add real-time histograms in Scanbox is…

Online cell segmentation in Scanbox
There is one hidden feature of Scanbox that has been around for some time, but I have not yet described. This feature allows for computer-assisted segmentation during an experiment. As you must already know, one way in which region of interests (ROIs) can be defined is manually. This process can be initiated by clicking on the Add button…
Read MoreReal-time, motion compensation in Scanbox
Our colleague Tobias Rose was recently asking about Scanbox’s ability to stabilize the motion of images and signals from regions-of-intrest (ROIs) in real-time. The goal of such processing is to be able to do experiments in closed-loop, and do very quick analyses on the neuronal responses, such as computing tuning curves on the fly. Below is a…

Here is a sneak preview of the new features to be released with Scanbox 2.0. Some of the salient additions include: Automatic stabilization: The system can automatically correct for rigid (x,y) translation in real time. Selection of regions of interest (ROIs): Allows for the selection of regions of interest that need to be tracked in real-time. After their definition,…
