Types of Image Sensors | Image Sensing

First Principles of Computer Vision is a lecture series presented by Shree Nayar who is faculty in the Computer Science Department, School of Engineering and Applied Sciences, Columbia University. Computer Vision is the enterprise of building machines that “see.” This series focuses on the physical and mathematical underpinnings of vision and has been designed for students, practitioners, and enthusiasts who have no prior knowledge of computer vision.

This series is fantastic. Very helpful, thank you

[@razorlord9330]

Wow.. brilliant.. great for beginners..

[@behyarsanaat3975]

I realy have never teached like this thank you very much my master...

[@andreshernandez5597]

Amazing explanation!! thanks!

[@SandeepKumar-qq8gs]

I found him Best lecturer on TH-cam.

[@annapurnasahoo6465]

Thank you sir for such a valuable lecture

[@VMGChannel]

Facinating! Thank you

[@narendraparmar1631]

Great😊

Subtitle is messed up. It's different from spoken.

[@bhuvan_983]

Thank you very much sir!

Thank you very much !

[@zwr9130]

Thank you, Sir

[@olandavinstiengen]

In CCD electrons are transported in columns not in rows. Then it reaches serial register. Its a massive difference

[@asadanees781]

Thanks

[@RynaxAlien]

Any cheaper sensors with good IR and UV sensitivity?

[@fanxingkong3409]

Can we do row scanning with CCD?

[@infoinadvance681]

We can build CMOS here, determination is required. Its a big market.

Sir torso hm hindi walo pr bhi dhyan digiye please

[@bra1nsen]

5:30 how is the voltage quantified to binary?

[@oosmanbeekawoo]

Bro binary is a bad idea! Imagine a grid of pixels each producing a binary response-you'll get an image of pure black vs. white! Like a chess board.
Instead you want each little square to read out the voltage as a continuous value.
So that high voltage means that place is very light, and low voltage very dark, and medium voltage about half grey.

[@otomackena7610]

with ADC

@@oosmanbeekawoo "Bro binary is a bad idea! Imagine a grid of pixels each producing a binary response-you'll get an image of pure black vs. white! Like a chess board." that's not how it happens. A 10 bit ADC it can represent 2^10=1024 discrete digital values so each photodiode can represent light intensity /analog signal with 1024 different levels or gradation.

@@otomackena7610 Yeah!

[@lixiang5148]

Hi, C in CMOS should be represented as “complementary” rather than “complimentary”? Around 5:13

[@Kashif_Javaid]

nit picking but you are right :)

[@harrysakata3082]

You mean complementary, not complimentary.
