matlab与python读取tiff文件

 

matlab

t=Tiff('IMG_3952.TIF', 'r+');
k = 1;
t.setDirectory(k);
img{k} = t.read();
src = img{1};
dst(:,:,1) = src(:,:,1) ;
dst(:,:,2) = src(:,:,2) ;
dst(:,:,3) = src(:,:,3) ;
figure;
imshow(dst);

 

python

#coding=utf-8
from libtiff import TIFF
from scipy import misc
##tiff文件解析成图像序列
##tiff_image_name: tiff文件名；
##out_folder：保存图像序列的文件夹
##out_type：保存图像的类型，如.jpg、.png、.bmp等
def tiff_to_image_array(tiff_image_name, out_folder, out_type):
    tif = TIFF.open(tiff_image_name, mode = "r")
    idx = 0
    for im in list(tif.iter_images()):
        #
        im_name = out_folder  + str(idx) + out_type
        misc.imsave(im_name, im)
        print (im_name, 'successfully saved!!!')
        idx = idx + 1
    return
##图像序列保存成tiff文件
##image_dir：图像序列所在文件夹
##file_name：要保存的tiff文件名
##image_type:图像序列的类型
##image_num:要保存的图像数目
def image_array_to_tiff(image_dir, file_name, image_type, image_num):
    out_tiff = TIFF.open(file_name, mode = 'w')
    #这里假定图像名按序号排列
    for i in range(0, image_num):
        image_name = image_dir + str(i) + image_type
        image_array = Image.open(image_name)
        #缩放成统一尺寸
        img = image_array.resize((480, 480), Image.ANTIALIAS)
        out_tiff.write_image(img, compression = None, write_rgb = True)
    out_tiff.close()
    return
