[Openimaj-discuss] Serializing ByteDSIFTKeypoints

[chalitha u. P. <cha...@gm...>]

Hi All,
I have extracted LocalFeaturesList<ByteDSIFTKeypoint> using Pyramid Dense
Sift in OpenIMAJ.
As indicated in API documentation, ByteDSIFTKeypoint implements Java
Serializable interface and there fore I would like to serialize keypoints
for latter use.
I tried to serialize keypoints to get a byte array. But when retrieving
key-points from the serialized object it loses all field values associated
with it.

I am using the following code for serialization

ByteArrayOutputStream baos = new ByteArrayOutputStream();

 ObjectOutputStream oos = new ObjectOutputStream(baos);

LocalFeatureList<ByteDSIFTKeypoint> features = psift.getByteKeypoints();

for (ByteDSIFTKeypoint byteDSIFTKeypoint : features) {

  oos.writeObject(byteDSIFTKeypoint);

byte[] bytes = baos.toByteArray();

}


Any help regarding how to correctly serialize keypoints is greatly
appreciated.

Thanks,

Chalitha
