图片处理

description: 解决清晰度不足/模糊的问题

图片处理-指定大小缩放

单独使用opencv或者PIL库的话都会出现不同程度的图片模糊，这里参考了文章：，同时运用了这两个库。最终清晰度明显提高。

import cv2, Image, ImageEnhance, time, osstrSourceFolder = raw_input("Input Source Images Folder:")
strOutputFolder = raw_input("Input Output Images Folder:")
nWidth = int(raw_input("Input Resized Width:"))print "resizing..."
StartTime = time.clock()
nCounter = 0
for file in os.listdir(strSourceFolder):strSourceFilePathName = os.path.join(strSourceFolder, file)CV2_ImgOriginal = cv2.imread(strSourceFilePathName)fRatio = float(CV2_ImgOriginal.shape[1]) / nWidthnHeight = int(CV2_ImgOriginal.shape[0] / fRatio)CV2_ImgResized = cv2.resize(CV2_ImgOriginal, (nWidth, nHeight), None, 0, 0, cv2.INTER_AREA)CV2_ImgResized = cv2.cvtColor(CV2_ImgResized, cv2.COLOR_BGR2RGB)PIL_ImgResized = Image.fromarray(CV2_ImgResized)PIL_ImgEnhanced = ImageEnhance.Sharpness(PIL_ImgResized).enhance(2.0)strFilename = os.path.splitext(file)[0]PIL_ImgEnhanced.save(os.path.join(strOutputFolder, strFilename) + "_resized.jpg", 'JPEG', quality = 95)nCounter = nCounter + 1print file, "processed"
EndTime = time.clock()
print "Processed", nCounter, "images"
print "Total elapsed time:", EndTime - StartTime, "Seconds"
