2013-12-27 07:09:56 -0600 | commented question | CvMlData read_csv in java Well it seems so.. Do you have any suggestion on the alternative method? The purpose is to construct a training set database so that I can apply the matching algorithm on the input. |
2013-12-27 05:31:10 -0600 | asked a question | CvMlData read_csv in java Hi I would like to ask how to read the csv file in java environment? As the opencv docs said, we can use CvMldata read_csv(), it is available for both C/C++ and Python. However, I searched on the docs for java, there is not the equivalent. Any suggestions, if you please? I would like to add the database for my feature matching algorithm. Thanks |
2013-12-18 04:27:51 -0600 | asked a question | Nearest Neighbors Ratio in Java Hi. I am doing the feature matching with OpenCV in Java and it gets stuck into one point. After performing the detection, descriptor computation and matching, the result is a List<matofdmatch> and I am not quite sure how to handle this to remove "bad matches". descriptor1 is Mat, which belongs to querry image and descriptor2 is train image. How should I handle the listofmatches to remove bad matches? It is a little different as in C++. Thank you very much |

2013-12-11 01:52:57 -0600 | commented answer | Compare pixel value with threshold in Java Yes, it is true, the function is handy. However there is one thing that is, all the value which is smaller than threshold is put to zero. In my case I only want to "locate" the point which is smaller than threshold. |

2013-12-10 12:21:28 -0600 | asked a question | Compare pixel value with threshold in Java Dear. As some algorithm requires, e.g Harris corner detection, it is necessary to compare pixel value with a defined threshold. I know that in C++ it can be done quickly with command But I have some problems doing it in Java, as I found only one command is Could you please let me know how to perform comparision in this case? Or in the doc of opencv, it is stated that the output could be int if but I am not sure what to do with the parameter byte[] data. Regards |
