Why webP image takes longer time in painting then jpeg?

I wanted to compare the rendering speed for webp and jpeg photos, so I tested it in chrome. Here is the result: Rendering time is less for webp and more time for painting. In the case of jpeg, painting takes less time, but idle time is long.
In the case of webP, it seems that it took more time for painting because it is lossless, but I don't know exactly. Can you explain why it came out like this? Thanks
Webp performance. Jpeg performance
I used test for chrome dev tool performance.
What exactly does painting time mean?
What exactly does idle time mean?
WebP took less total time, so is webP loading faster?

How to upscale my low res image to high res image using any software?

I have a low-res image in the attachments section, would anybody explain me technique to make it high-res image ? It would be really helpful if you could show me how can I improve resolution, quality and bring out the elements from the image clearly.
As far as I know there is no way to change the resolution upwards simply because your image lacks the data to do so. There is no program that would 'calculate' the pixels to more then there are. Ether find the source of the image and take a larger picture or have a higher resolution rendered. You could -trace- the image in illustrator and abandon the exact composition of the artwork.
I know "Vector Magic" Paid software. Give it a try.
I also suggest tracing the image in illustrator and that way you will create a new image with higher pixel counts. It is not possible to "add" any pixels in your current image as it originally does not have additional pixels.
Also, please specify if you want to improve resolution while enlarging the picture or you wish to use it as the same size? This will help in getting a to the point answer.

Tango color frames not of best quality, looks like up-scaled from lower resolution. Is it a Tango hardware limitation?

I obtain color frames from TANGO_CAMERA_COLOR. Frames are not of the best quality - looks like they are up-scaled from lower resolution.
This can be easily seen by comparing video quality from standard Android Camera app and "Project Tango Native Augmented Reality" sample app, running on the same device.
Questions: is it what intended to be? If so then why?
Is there a way to improve quality, of if there is a plan to improve quality in future Tango releases?
I set config_color_iso to 400, default exposition time.
Each depth frame has corresponding color frame with the exactly same timestamp. Infrared illumination (artefacts) are seen at just a very few color frames.
You may want to stick with the images coming out of Tango
1) If you snag another camera, or grab the camera directly, then Tango depth information stops coming.
2) More importantly to my eyes, it is the images from Tango that are the source of the point cloud - anything you want to do with coloring cloud points and surfaces and having the faintest hope of success would do better with these images
3) Trying to offload the image stream in real time requires JPEG compression if you're going straight to the cloud - raw images from tango are 1280x720, so they way in at about a megabyte each before compression

Converting a low resolution image into 300dpi image to be able to accept Elsveir (or IEEE) regulations

I want to submit some images to IEEE journals. there stand is image should be in at least 300dpi. I originally created my image using screenshot. its original size was 392*143 (pxels) and resolution was 96*96 (dpi).
then i used GiMP and go Image > scale image > X and Y resolution to (300)
then i export it.
yes, in the property of the image it shows now resolution as 300*300 dpi.
when i open the image, I can not see that it has high resolution quality that my original. because still to the computer screen my original image look good.
Did I do something wrong? should I change the size when changing the resolution, but i feel if i give a larger size than original size then the new image might verse.
can anyone tell me, how can i get a quality high resolution image (at least 300 dpi) using low quality image. thanks

Animated Gif Optimization

I wonder, what is the best solution to compress an animated gif without loosing too much quality?
Is there a software or a website (like tinypng.org does with png) that can really help?
Or am I stock with what I got after the Photoshop export?
gifsicle (GUI) is such program although it optimizes mostly losslessly.
GIF file size is most dependent of pixel dimensions of the animation. Resampling to lower resolution may significantly reduce size.
