If all values R,G and B are equal, then you get gray as color. I work with a USB camera and the resulting array. I want tocreate a RBG image which will be the overlay of the three images. I was just wondering if you are asking a question or providing a solution. Your post read as a question so I wasn't sure. All you need is " draw unflattened pixmap " and send it to an 2D image indicator. United States.

Did you mean:. Convert an 8-bit grayscale image into an RGB image. Is it possible, within Vision Assistant, to convert an 8-bit grayscale image into an RGB image by applying the gray level pixel value to the three color components: red, green, and blue? Mensaje editado por ispbarum.
Message 1 of 9. Re: Convert an 8-bit grayscale image into an RGB image. Proven Zealot. Hi ispbarum, to convert an 8 bit grayscale image to RGB you only need to write the value to all three components.
Hope it helps. Message 2 of 9. Active Participant. It's weird that you can only change to other grayscales in the Vision Assistant.

Custom Grayscale Weights User-defined Weights Check this to use custom image to grayscale conversion weights. Red Red weight coefficient.
Green Green weight coefficient. Blue Blue weight coefficient. Image to grayscale converter tool What is a image to grayscale converter? This tool converts color images to grayscale images. It removes all information in color channels and only leaves gray color information in the output image. As a result you simply get a black and white image. As there are many ways how to remove color from an image, you can choose the conversion algorithm or enter your own constant weights for how much grayscale to extract from each color channel.
Image to grayscale converter examples Click to use. Grayscale an image using a preset formula.RGB Value:. The RGB color model is used to describe the way in which colors in different hues and tones are displayed by differing the amount of red, green, and blue light that is displayed through the pixels.
The pure form of red, green, and blue are displayed as follows:. This pure form of display is represented by the following encoding: pure red0, 0pure green 0,0and pure blue 0, 0, When RGB encodings are presented, the first value always represents the amount of red, the second the amount of green, and the third the amount of blue.
A range between 0 and is used in the encodings. Grayscale images do not include any color. They are given in the range of shades that lie between black and white. For example, white is represented by,black is represented by 0, 0, 0, and medium gray is, The higher the number is, the lighter the gray becomes. RGB encodings can be converted to grayscale values by converting the RGB encoding into a set of three equal numbers that represent the range on the black-white spectrum on which the color appears.
To transform a color into its corresponding grayscale value, you need to calculate the average of the R, G, and B values using a weighted approach. It is important to note that the colors are not equally weighted. As pure blue is darker than pure red and pure green, it is allocated the least weight.
Computation Example: Let's say we have a color that can be represented by the RGB value 70, The weighted average for our RGB color 70,is as follows:. When the weighted average does not equate to a whole number, we round it to the nearest whole.

You also need to install Numpywhich can be done with pipthe Python package manager, by sending the following command on the command line:. To get started, we need to import the cv2 module, which will make available the functionalities needed to read the original image and to convert it to gray scale. To read the original image, simply call the imread function of the cv2 module, passing as input the path to the image, as a string. For simplicity, we are assuming the file exists and everything loads fine, so we will not be doing any error check.
Nonetheless, for a robust code, you should handle these type of situations. Next, we need to convert the image to gray scale.
As first input, this function receives the original image. As second input, it receives the color space conversion code. Now, to display the images, we simply need to call the imshow function of the cv2 module. This function receives as first input a string with the name to assign to the window, and as second argument the image to show. This function receives as input a delay, specified in milliseconds.Triac dimmer module
To test the code, simply run the previous program on the Python environment of your choice. You should get an output similar to figure 1, which shows the original image and the final one, converted to gray scale. Try using a loop a for loop if you know the size of the folder or a while loop to extract each separately.

How to convert grayscale to rgb? Ynne on 16 Jan Vote 0. Commented: Image Analyst on 8 Oct I used the following script to convert grayscale image to rgb. The problem is that when i execute imshow im it still without colors but size im is 3 I'm confused, how can i obtain image with colors?

Python OpenCV: Converting an image to gray scale
So the red, green and blue components are identical and so the image will still be in "grayscale". Thks, yes it's clear, but what shall i do instead? Image Analyst on 16 Jan We have already define the RGB color model and gray scale format in our tutorial of Image types.
Now we will convert an color image into a grayscale image. There are two methods to convert it. Both has their own merits and demerits. The methods are:. Average method is the most simple one. You just have to take the average of three colors. Since its an RGB image, so it means that you have add r with g with b and then divide it by 3 to get your desired grayscale image. If you have an color image like the image shown above and you want to convert it into grayscale using average method.
The following result would appear. There is one thing to be sure, that something happens to the original works. It means that our average method works. But the results were not as expected.
We wanted to convert the image into a grayscale, but this turned out to be a rather black image. This problem arise due to the fact, that we take average of the three colors. Since the three different colors have three different wavelength and have their own contribution in the formation of image, so we have to take average according to their contribution, not done it averagely using average method.
Right now what we are doing is this. But in reality thats not the case. The solution to this has been given by luminosity method. You have seen the problem that occur in the average method. Weighted method has a solution to that problem.
