Read Multiple images on a folder in OpenCv (python)

Question

I want to read multiple images on a same folder using opencv (python). To do that do I need to use for loop or while loop with imread func

Answer 1

def flatten_images(folder): # Path of folder (dataset)

images=[]                             # list contatining  all images

for filename in os.listdir(folder):

    print(filename)

    img=plt.imread(folder+filename)  # reading image (Folder path and image name )

    img=np.array(img)                #

    img=img.flatten()                # Flatten image 

    images.append(img)               # Appending all images in 'images' list 

return(images)
