error: (-215) ssize.width > 0 && ssize.height > 0 in function resize

  • 2

I am building an image processing classifier. This line is giving me an error:

input_img_resize=cv2.resize(input_img,(128,128))

The error:

('error: /io/opencv/modules/imgproc/src/imgwarp.cpp:3483: error: (-215) ssize.width > 0 && ssize.height > 0 in function resize')

My code:

PATH = os.getcwd()
# Define data path
data_path = PATH + '/data'
data_dir_list = os.listdir(data_path)

img_rows=128
img_cols=128
num_channel=3
num_epoch=30

num_classes = 67

img_data_list=[]

for dataset in data_dir_list:
    img_list=os.listdir(data_path+'/'+ dataset)
    print ('Loaded the images of dataset-'+'{}\n'.format(dataset))
    for img in img_list:
        input_img=cv2.imread(data_path + '/'+ dataset + '/'+ img )
    
        input_img_resize=cv2.resize(input_img,(128,128))
        img_data_list.append(input_img_resize)

      Well, obviously this line
      input_img=cv2.imread(data_path + '/'+ dataset + '/'+ img )
      returns an empty array.

      You should check whether the image exists first before reading. And it is better not to use string combination to join file paths, use python os.path.join instead.

      image_path = os.path.join(data_path, dataset, img)
if os.path.exist():
    # Do stuff
