Results

In our experiment, we take three groups of LDR pictures and try to construct three HDR pictures from them. For each group of these pictures, we take 6 LDR pictures with different exposure times. We’ll display the response curve for each color channel: red, blue and green and our final HDR picture.

Comment: It’s impressive to see the details both of the light and of the clothes. For these kind of pictures, it’s always easy to lose the details of the light since the pixel values of the area around the light will get saturated. But, through HDR, we could keep the details of the light without losing any other details.

Final HDR picture for Group 2

Comment: Once again, we almost see the details of the lamb. Although it’s distorted a bit, we know there’s something in it, instead of just completely white for the whole area. What’s amazing is that we could clearly see what’s going on in the background. All the details of the bags are clearly revealed.

Comment: Once again, we could see a lot of details both in over-exposed area and in under-exposed area. For example, we could see some words on the white container on the right hand side of the lamb. It’s impossible for us to see those words when we take a picture with relatively large exposure time. Similarly, we could see the details in the dark area. For example, we could see that there’s a purple/blue stuff lying on the black bag. However, it’s likely that we’ll barely see it when the exposure time of the picture is relatively small.

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
