How can I apply my filter to all jpg images in a single folder after another.
A loop like check how many data then load pic1 (then filter and store result) going to load pic2...until pic.last
I´m using imread to load and imwrite to store after the filter for 1 image atm
i'm running an object search by using different color-filter options this works fine. I´m chemist and new to python.

I am trying to work on a computer vision model but the dataset is completely new to me. It is as shown :
Dataset folders image
I have to extract each image in every folder and combine them into one train and one test folder. This is to get the filepaths of each image which I will use to decode jpeg. Can someone help me with the same ? Basically I need the filepaths of each image in one list. But the image names are also duplicate in each folder.
I am working with extracted images from videos and I was able to accomplish that and I have an annotation xml file for the extracted images. As I am new to computer vision. I am confused about how to proceed from there and how to add the xml file to my extracted images. I want to prepare my data for DL model. Any help would be appreciated.
I am assuming you are extracting images from video based on video's FPS and each extracted image is stored in images/ folder.
Use Annotation tool like CVAT, labelimg, etc and open images/ using these tools.

I want to save an image/an array as an OIB File.
I have tried using the oiffile library. I am able to open and read OIB files, but I want to save an image as an OIB File.
Since oiffile uses cv2 structure for opening/closing images (via numpy arrays), so you might be opening the image using imread(). Then you can use imwrite() for saving/writing the image file to a destination path.

I was trying to apply the tutorial for camera calibration however I receive the error that 'gray' is not defined when I use the function cv.cameraCalibrate.
I am afraid that the images are not being read ? Even when I tried to load some checkerboard photos from a directory , still the same problem
you can find the link for the tutorial here
https://docs.opencv.org/3.4/dc/dbb/tutorial_py_calibration.html
The images are not able to load. As a result, for loop is not iterating over the array of images and hence the gray variable inside the loop is never been initialized. So it is showing undefined for gray variable.
Check if your images array is empty then cross-check the path from where you are loading the images.
This is an error you get when the images are not imported correctly.
Check whether the images you are trying to import are in the same folder as your python script.
If they are not and you don't want to move them, you can specify the path to the directory you want the script to look for.
I am writing a photomosaic python application.
I want to know how to create the final image (.jpg) using multiple smaller images from a pool of images with Python/PIL. I have the order in which I want the various images to be in a 2-dimensional list.
