Question

files2 = [f for f in listdir(dstpath) if isfile(join(dstpath,f))]        
for image in files2:
    img = cv2.imread(os.path.join(dstpath,image))
    equ = cv2.equalizeHist(img)
    dstPath2 = join(dstpath,image)
    cv2.imwrite(dstPath2,equ)

我有一个由jpg格式的灰度图像组成的文件夹，但是当我运行上面的代码进行直方图均衡时，它会给我上面提到的错误。请帮忙

Answer 1

imread默认情况下以彩色模式加载图片。尝试使用img = cv2.imread(your_image_path,cv2.IMREAD_GRAYSCALE)代替

"""
import cv2
import os
from os import listdir,makedirs
from os.path import isfile,join


path = r'' # Source Folder
dstpath = r'' # Destination Folder


try:
    makedirs(dstpath)
except:
    print ("Directory already exist, images will be written in asme folder")

# Folder won't used
files = [f for f in listdir(path) if isfile(join(path,f))] 

for image in files:
    try:
        img = cv2.imread(os.path.join(path,image),cv2.IMREAD_GRAYSCALE)
        **imgnew=cv2.equalizeHist(img)**
        dstPath = join(dstpath,image)
        cv2.imwrite(dstPath,imgnew)
    except:
        print ("{} is not converted".format(image))

我所做的只是添加了histeq功能，而我的文件转换为灰度

histogram.cpp：3915：错误：（-215）_src.type（）== CV_8UC1函数cv :: equalizeHist
