idk what happened to the readme but i had to go look at an old commit were the documentation is in it. I dont like the website and it isnt convienent. also its very slow. issue #117 mentioned parallel threading. Why was this issue closed. its not fixed and its still an issue. Threading isnt difficult if its high level enough. it should be an argument along with what the deley should be to spawn a

darkflow_error

I created a virtual environment using conda and I installed darkflow and it worked pretty well. I later exported the environment to try it on another computer to verify that everything works. But conda doesn't install the darkflow even though it exists on the requirement.txt

This feature is implemented in many graphics hardwares at least of most gaming consoles. Adding this feature would enable ImageSharp to natively allow for these specifications of graphics hardware to be supported out of the box.

As per OpenCV naming and implementation this feature is most likely known as "Remapping" or "Point remapping". So as the naming goes, it should incorporate either one.

Issue description

Is the matrix-matrix multiplication function (Dot(matrixA, matrixB)) documented anywhere? I can't find the documentation on the accord-framework.net website and the code appears to be generated from .tt files.

Function label2rgb uses a fixed number of colors by default

When we have a label image having more than 10 colors, it would be useful to associate distinct colors to the different labels.
Background: I use a program that can create labels by reading

It tells you to get version 3.0 of the SDK, which doesn't have libwrapper.so, so you get an unhelpful failure to find halide_hexagon_remote_load_library (because init_hexagon_runtime doesn't check if host_lib is non-null). This is hard to debug, because host_lib is null not because libhalide_hexagon_host.so isn't found or isn't in the path (it is!) but because a dependent library - libwrapper.so -

Hi,
I went through the documentation and couldn't find anything about using imgproxy with a SPA framework like vue. Are there any examples or guides on this?

If I understand correctly imgproxy is ment to be used serverside because of the encryption aspect. Would love to know about any best practices on how to implement it in a SPA scenario.

Thank you

I am trying to test dnn-detection Code

Expected behavior

Builder exists and works for argument : keepAspectRatio
(feature is precious because round on reduction will have a few pixel difference with requested size)
Example : expecting 500x1000px and got 499x1000px

Actual behavior

keepAspectRatio arg is not mentioned in examples

##Suggestion of example
Thumbnails.of(dir_in.listFiles()).size(width, height).keepAspectRati

Gamma correction is among the things most often done wrong by graphics programming novices. It's almost as bad as missing scene-related color transforms and linear volume sliders in the average video game. The code example in the readme should definitely mention to adjust.Gamma(img, 1/2.2) before doing any color mixing and adjust.Gamma(img, 2.2) before saving back to file (for as long as _bild

You can’t perform that action at this time.
