My father solved this problem before I was born in 1969. Peel the top of the banana as if you are going to eat it. Put peanut butter on the knife and wipe it on the top of the banana. Take a bite. Continue until the banana is gone. Ignore the bread. It more keto that way anyway. If you really want to use the bread, mash the banana and spread it on one slice, spread the peanut butter on the other and put them together…

Or most optimal spread peanut butter on slice of bread fold bread around banana like a hotdog bun.

I am an emergency physician without any formal software training and for the last three months I’ve been trying to build a program that segments the wall of the heart from an ultrasound video and then identifies regions that aren’t moving (an early sign of heart attack). There are many similarities between this man’s project and mine. And if I had his knowledge I may have cracked my problem by now and would have new…

The problem of finding the Centreline of the banana is similar to an issue you get in the GIS domain when rivers are captured as polygons.

Although it's not a straightforward process a series of Vorononoi polygons makes a pretty good Centreline. I think it might work for bananas.

Lots of effort to arrive at the wrong answer! An optimal pb + b sandwich must contain not just circle pieces, but pie slices of circular slices at well. All those gaps left by the circles could be filled with little fractions of circles.

Bah. no 2 dimensional model can be taken seriously here, the problem is 3d and therefore much more complicated. insert $500k grant proposal

Wow I sometimes I understand the downvotes but this one doesn’t make any sense...

Do you realize that there are thousands of scientific publications in medical image processing that address exactly the same concrete problem that you have?

Yes, however much of that research is for formal ultrasound obtained by a professional sonographer with an expensive machine. I'm interested in bedside ultrasound performed by an emergency physician with a mediocre machine (eg butterfly).

It seems the primary way to detect regional wall motion abnormalities is with speckle tracking, which requires way too much post-processing for a clinician.

A system that segments the left ventricle and finds akinetic regions in realtime from a parasternal long axis view or an apical four chamber view would be pretty nifty.

If you know of a paper or system that does this now then please let me know. I would love for someone else to have solved this, haha.

Fast.Ai is incredible. Love it. I've bumbled my way through it and was able to make a unet learner trained from this dataset -- https://www.creatis.insa-lyon.fr/Challenge/camus/ -- in order to segment the left ventricle from an apical four chamber view. It's a start, but I still have a long way to go.

Excellent project. Very well written and executed. Love it. I've found that I can get excellent consistency in coverage by slicing the banana vertically to get long rectangular slices and then laying the slices side-by-side - generally about 4-5 across.

He addresses people like you:

If you were a machine learning model (or my wife), then you would tell me to just cut long rectangular strips along the long axis of the banana, but I’m not a sociopath.
