Wrong lables

Opened this issue 4 years ago · 6 comments

Hi,

I have been trying to find labels just for tabular data. First of all there are too many None values in image column. I have tried filtering based on category_id=4 i.e., Table. After filtering, I got the Bbox and created a seperate column and tried seperating only the filtered images. When I looked into the filtered images there were too many images in which there was no table or table like structure present. Then, I tried creating the bbox over it and was getting the incorrect bounding box which is covering the partial table or in many cases no table at all. I am reading the bbox as (xmin ymin w h). Have tried other variations as well. Am I missing something here. Please help

Hi ajjimeno,
PFA two examples would provide more if required :-

Image name:- PMC522826_00007.jpg
BBOX :- [35.89, 130.41, 514.03, 602.48]

Image Name:- PMC2248230_00005.jpg
BBOX:- [36.0, 73.05, 522.01, 66.05]

Image Name:- PMC1410770_00002.jpg
BBOX :- [123.5, 59.5, 390.0, 619.0]

This is a partial table covering example. I am yet to come across an example which is perfectly annotated. Enough to create the doubt on my approach. Let me know what am I missing here.

Thanks a lot. :)

Hi, we provide the following jupyter notebook as an example for displaying bounding boxes for the different objects in the images and annotations. I am wondering if you had the chance to have a look at it and it helps. https://dataplatform.cloud.ibm.com/analytics/notebooks/v2/43cb95d9-6c3e-479c-a189-8c9ff3524ec1/view?access_token=bb8ce645cf114b5f5512ae2eb9c7badcf0927f313e8f76b8138d0701289484e6&cm_sp=ibmdev-_-developer-exchanges-_-cloudreg

Hi, I had the chance to go through the given notebook and used to same code on the said examples. But the results looked identical 🙄

Answer 5 · 2020-12-17T05:35:42.000Z

I have checked those examples and I cannot see anything different to what you find, the data set has some noise, and my belief is that you have identified some of the noise in the data set in the examples you are considering. Please, let me know if you haven't found examples that you are after.

maybe a lot. I have tried filtering 5 images based on category_id=3, not correct at all.
