Isolated chloroplast membranes of the unicellular photosynthetic alga Chlamydomonas reinhardtii were cryofixed, freeze-fractured, and surface replicas observed by transmission electron microscopy. The
One of the principal challenges in counting or segmenting nuclei is dealing with clustered nuclei. To help assess algorithms' performance in this regard, this synthetic image set consists of five subs
This image is one from a set of 40nm thick serial sections through part of a Golgi ribbon from a normal rat kidney cell, generated using transmission electron microscopy following incubation at 15°C t
