How to make a simple PPM image in C++. How to add filters to PPM pictures in C++. Here are some test p3 images you can use with this! github.com/fer...
This was amazing!' I have been wanting to learn about manipulating images with C++ but I was scared it was hard. But this video was very easy to follow and was extremely useful. Thank you very much!
Interesting content, amazing channel, cool teacher, I can watch u the whole day, God bless u and bless America for creating this beautiful world that is called the internet.
Dude your videos are amazing and your teaching style is awesome, make more of these please. I have a questions: -> Will you cover some sort of graphics library. Something like processing in java, in future. And a request, could you please increase your audio volume it's quite low.
Hey Praveen, thank you I appreciate that! I will be covering some c++ graphics libraries like SDL2 which overlaps OpenGL and maybe a few others soon (wxwidgets for windowed applications). I will be staying away from Java graphics libraries though.
Hey i want to know where you open this ppm file i want to see this but unable to see in window 10 os can you give me some hint where i can see this ppm file format.
I am taking C++ as my new language after working on the front end for over 7 years. I was always interested in low level code and your video helped a lot. The only thing I don't understand is why .ppm files opened in VS code show numbers and not binarires and why jpg files dont show digital or binary content?
Fantastic video, thanks so much! Do you know where I could find information on video programming? I.e., how to stitch together generated images into an avi, mp4, mpeg, etc...?
I had an idea that I can't quite flesh out. I want to generate images based on hash values. Using sha512, you get an 8x8 image but it needs to be scaled up to be practically viewable. I haven't been able to find or come up with an algorithm that works without blending the grayscale pixels. Any help would be appreciated.
How hard do you think it would be to take an image, use the two for loop strategy to take in the "brightness value" of each pixel, and then generate some sort of ASCII art interpretation of the image? thanks
Hey Flippeh, It would add a degree of complexity. In my opinion, it might be easier to work with by changing all the colors to a gray scale. Then grouping them and converting them to ASCII.
I would like to know how to identify data in a picture more tha colors. for example like to identify if what i am reading is a bird , a fish, a tree and so on. is there any advanced documentation you can suggest ? thanks in advance
Hey Jose, you would need to look into OpenCV, which stands for open computer vision. Essentially, you train the algorithm by giving it pictures that look like what you want to identify so it can find it in new pictures!
Hello, there! Sorry that I'm late, but thanks a lot. I turned stuff in this video into a library & portted it into C instead of C++. If you can, please make another video, about stuff such as cutting, sharpening, flipping & rotating. I would really appreciate it
Hey Thomas, I apologize for not getting back to you sooner. You can use an external package called ImageMagick (imagemagick.org) to convert these images (that is what I did). It can be used programatically or via the command line (I used it through the command line).
It is actually pretty simple to do, you just have to add the red, green, and blue values and divide by 3. Then use that value for the r, g, b values. Try doing this first and see what you come up with!
