This month our third Wednesday Lectureship program features Dr. Yair Rivenson an Adjunct Professor at UCLA giving a talk titled "Beyond classification: computational deep learning microscopy"

Dr. Rivenson received his B.Sc. (cum laude), M.Sc. and Ph.D. from the Electrical and Computer Engineering Department, Ben-Gurion University of the Negev, Israel.  During his Ph.D. he was working on implementation of computational imaging techniques for coherent imaging applications. Following the conclusion of his Ph.D. in 2013, he has joined Prof. Zalevsky’s Electro-Optics group in Bar-Ilan University, where he was gradually exposed to the field of biomedical imaging. At July 2015 he joined Prof. Aydogan Ozcan’s Nano/Bio photonics Laboratory at University of California, Los Angeles (UCLA) as a postdoctoral fellow through the Marie Sklodowska-Curie Global Fellowship (Bar-Ilan University/UCLA). His current research topics include design and implementation of deep learning inspired hardware and software for computational imaging applications.

Beyond classification: computational deep learning microscopy

In recent years, deep learning has redefined the state of the art, surpassing human performance for a myriad of classification and recognition tasks. We will discuss the emerging field of application of deep learning for computational microscopy, with the unique challenges and opportunities created by this framework. Amongst the applications, we will demonstrate enhancement of brightfield benchtop microscope images, extending their resolution, depth of field and field of view. We will then demonstrate the use of deep learning to super-resolve beyond the diffraction limit and perform cross-modality imaging in fluorescence microscopy, i.e., transforming an image acquired using one microscope to match an image acquired using a different microscopic imaging modality, while improving the signal-to-noise ratio, throughput, and reducing phototoxicity.

We will also discuss the extension of the framework for mobile, smartphone-based, microscopy, matching the imaging performance of a smartphone microscope to a laboratory grade benchtop microscope, eliminating spectral distortions, increasing signal-to-noise ratio and enhancing resolution, even for highly compressed images, that can be used in devices deployed in low resource settings areas. Other than that, we'ill demonstrate the application of virtual histopathology staining, where a deep network can learn how to digitally stain a single, label-free (unstained), autofluorescent image to match the same image of the tissue section as it would have been histologically stained (for example, using H&E or Masson’s Trichrome stains) and imaged using a brightfield microscope. By that, this technology enables a paradigm shift in the diagnostic workflow, bypassing the laborious and lengthy process of histochemical staining, while allowing tissue preservation. 

Finally, we’ll demonstrate how deep learning can be used to substantially increase the throughput of coherent (such as holographic) imaging systems and demonstrate some of the opportunities that deep learning brings to that field.

amoebaThe Pond Life program is undoubtedly one of our best attended and most exciting hands-on meetings! This is the event that you bring in your microscope (if you have one) and a samples of pond water obtained from your neighborhood: basically pond water, ditch water, puddles, fountain water or any other natural water samples. If you don’t have a pond source then just come and enjoy the collections brought in by others. We hope to have water samples from all over southern California. This is a fun, hands-on meeting, and one at which we'll hope to see new and exciting discoveries.

Suggested equipment list: water samples, microscopes, illuminators and pipettes and tools to play with the water samples. (Extra microscopes are always a good thing to bring for guests to use.)

If you have books or publications that identify Pond Life then do bring those along as well.

Here's a video by Tom Jones showing pond water organisms filmed at the Microscopy Society of Southern California, May 2015, Pond Life Meeting in Santa Monica, CA. The specimen is lake water collected from Lake Gregory, in Crestline, CA., with a 20um pore size plankton net. Two different microscopes were used. The Rotifer is probably Synchaeta sp. and is shown in dark field using an Olympus BH-2, 1.67x projection eyepiece, DCD condenser, mag changer set at 2x, and a DPlan 20x objective. The second and third parts of the video show Stentor sp., also in dark field, using an Olympus SZH Research Stereo Microscope, DF Plan 1x objective, ILLD illuminator base set to dark field, SZH-PT phototube with a 1.67x projection eyepiece. Zoom magnification was set at 64x. A Tucsen TrueChrome II camera at 1080p was used for all parts of the video.

This is the annual Exhibition Meeting of the Society. This is one of the best events of the year and is a great deal of fun. Each member is encouraged to bring along an exhibit to share. Anything associated with microscopic subjects is welcome. Your exhibit could be simple, for example you could set up your microscope with your favorite slide. A projector will be provided for those bringing 35mm slides. Posters and display boards are also encouraged, along with the usual sales table. Please remember to bring a label or piece of paper with a brief description of your exhibit.
