2017-05-11 13:26:15 -0500 asked a question shape localization and recognition

There is a set of images, each of which contains different shape entities, such as shown in the following figure. I am trying to localize and recognize these different shapes. For instance, adding a bounding box for each different shape and maybe even label it. Is that possible to fullfill this task using opencv? image description

2017-02-22 11:52:52 -0500 asked a question image sampling and its implementation in opencv

I have a set of image pairs, i.e., {A, A’}, {B, B’}, {C,C’} etc.

Given an image A, for instance, 256*256, are there any sampling mechanisms to generate a small image, i.e., 128*128, that can capture the global contexts of original images.

At the same time, I would like to keep track information of those sampled pixels. For instance, if pixel[I,J] in A is selected, I need to track it because I need to select the same pixel of A’.

In other words, I need to generate a set of smaller image pairs based on these large image pairs. The sampling mechanism, however, is based on A, B, C, etc.

2017-02-19 18:09:25 -0500 asked a question the dtype of read image

Hi,

I have read an image as follows

image = cv2.imread('/data/cat.jpg',cv2.IMREAD_UNCHANGED)
print('image dtype ',image.dtype)

The dtype for the read image is uint8, how to transfer it into float32 or what kind of read option can enforce the read image as float32.
