Re: Using ImageMagick to identify a person walking over grass for a fixed camera in a sunny day

Re: Ubuntu 14.04 and ImageMagick

I am having problems to update IM in Ubuntu 14.something either.

I need 6.8.9, so I wonder how you installed this intermediate version?

Re: Converting PDF page to image missing accentuated characters

By the way, how did you update the version 6.7.7 to 6.8 in Ubuntu?

I tried to follow some of the suggestions present on this website, but those did not work.

Could you please give a clue on how to update the version in Ubuntu 14.something?

Re: Using ImageMagick to identify a person walking over grass for a fixed camera in a sunny day

I am silent because I am struggling to update my IM in Ubuntu. I still have 6.7 instead of 6.8 and the topics related to that are not helping much. Regarding how I define the shape of a human, I guess the important thing is to differentiate a human from other type of moving objects, such as a dog or...

Re: Using ImageMagick to identify a person walking over grass for a fixed camera in a sunny day

I will study these ideas. How likely will my software be able to raise a warning in case of detecting a human being? How about applications for blind people? Do you invision the use of ImageMagick to help blind people? I am not talking about OCR techniques, which are very well known. I am focused on...

Re: Using ImageMagick to identify a person walking over grass for a fixed camera in a sunny day

Wow! This is great.

I think I can later select the object by its shape.

Now the issue is the variations of contrast... Do you think ImageMagick has "image registration" capabilities?

This sounds as a powerful technique to keep the image steady, no mater the ilumination issues.

Re: Using ImageMagick to identify a person walking over grass for a fixed camera in a sunny day

This is the information provided by ImageMagick "identify":

a0.jpg JPEG 320x240 320x240+0+0 8-bit DirectClass 14.4KB 0.000u 0:00.000

transparent_dog.jpg JPEG 320x240 320x240+0+0 8-bit DirectClass 15.5KB 0.000u 0:00.000

So, both images are 320x240.

Thanks for your help!

ok. Sorry. I didn't realize the issue.

I will separate the images as follows:

Re: Using ImageMagick to identify a person walking over grass for a fixed camera in a sunny day

I just realized I lost resolution after transferring to Photobucket. Since that image is a way too low resolution, below you will find a single row where you can see that the dog image is getting confused with the grass (the color of the dog seems to be similar to the grass).

Re: Using ImageMagick to identify a person walking over grass for a fixed camera in a sunny day

I am getting:

convert.im6: unrecognized option `-connected-components' @ error/convert.c/ConvertImageCommand/1107

Perhaps a problem with the IM version?
