Detect a color.
color is meta-data. People need to understand that when they use color to differentiate cells. Excel has very limited capabilities of evaluating color. Even the human reader of the spreadsheet cannot tell why a cell is blue and another cell is green. It requires a legend, a system, a frame of reference.
In this post, I will show you how to build your own color recognizer using Python. This process is also known as “Color Detection”.

One commonly used model is RGB, which represents colors by combining red, green, and blue intensities.
The surface of the apple is reflecting the wavelengths we see as red and absorbing all the rest. An object appears white when it reflects all wavelengths and black when it absorbs them all. Red, green and blue are the additive primary colors of the color spectrum.

We can detect and extract colors present in an image using the inRange() function of OpenCV. Sometimes, we want to remove or extract color from the image for some reason. We can use the inRange() function of OpenCV to create a mask of color, or in other words, we can detect a color using the range of that color. The colors are stored in an RGB ...
Color Harmony refers to matching and harmonious colors that are aesthetically pleasing when combined together. They are derived by geometric relationships within the color wheel. Our color picker can automatically generate these based on the color you pick.
Step 2 – Detect the color from the input image and create a mask: At first, we’ll detect green objects in this image and then we’ll detect yellow objects. OpenCV reads the frame as BGR colorspace. But to detect any color, first, we have to convert the frame to HSV colorspace using cv2.cvtColor function.I want to detect a certain color, move the mouse to this specific color and right-click it. This way it should click all the coins on the screen. When the color/coin is not in the sceen, the left or right arrow-key should be pressed for 3 - 5 seconds (this will change the camera, in game.)

The following color codes are supported: Hex (e.g. "#FF0000" or "#FFF") RGB (e.g. "RGB (255,0,0)") The supported RGB codes correspond to the 24-bit system where each component ranges between 0 and 255 (8-bit encoding).Try countNonZero() instead, or numpy.count_nonzero() and this would detect any pixel of the given color. I think it's probably best to have a minimum detection area (well, depending of the OP) @MarkSetchell yes that's totally true, I didn't know the countNonZero () function, thank you!
I want to detect a specific color say, blue, from a live video stream. I have written the following code which displays the live video stream and change it into HSV and grayscale.

This uses the same color wheel as the RGB model, but make no mistake – these are two different color models. Unlike RGB, CMYK is a subtractive color mixing model. Colors are produced by subtracting light from paper by adding pigmented ink to a white …What you want to do is find the angle of the color vector of the pixel to the color vector of the ideal by using the dot product. For example: Theme. Copy. blue = [0 0 255]; pixel = [10 10 200]; ang_thres = 25; % degrees. You should change this to suit your needs. ang = acosd (dot (blue/norm (blue),pixel/norm (pixel)));You should instead of it convert your RGB values to LCH system and extract C (=chroma) or to CIELAB system (=Lab in Photoshop) and calculate sqrt (a^2+b^2). Those systems are developed to be more linear in predicting what's seen. For grey C=0 and a=b=0. This is of course a lie if the screen isn't color calibrated.
The human eye sees color over wavelengths ranging roughly from 400 nanometers (violet) to 700 nanometers (red). Light from 400–700 nanometers (nm) is called visible light, or the visible spectrum because humans can see it.Light outside of this range may be visible to other organisms but cannot be perceived by the human eye.

We need to calculate the delta and compare it to the threshold because for each color there are many shades and we ...'Color 1 Is Lighter' : 'Color 1 Is Darker'; //Comparing the two converted rgb, the greater one is darker As pointed out by @Some Guy , I have modified my function for yielding a better/accurate result...I want to implement color detection in Android.
