OpenImaj OutOfMemoryError during Resize Process

QUESTION

OpenImaj OutOfMemoryError during Resize Process

Asked 2019-May-02 at 01:30

I have two photos, one zoomed in and the second a large, wide angle photo. Consider the first image a crop of the second(though it is not). I select a single pixel from each photo that represents the same thing in both pictures (say a man's nose). I overlay the first picture, with some transparency, on top of the second picture aligning the two selected pixels?

Now I want to scale the second image until the first image essentially disappears because the scale of the second image matches the scale of the first.

I am using OpenImaj and have successfully accomplished this using MBFImage.overlayInPlace(). The problem I have is that when I use ResizeProcessor to scale the second image, I get an "OutOfMemoryError: Java Heap Space" if I have to scale the second image too much ( >5x ).

I have bumped up the -Xmx to 12G using JDK 12 64bit. I have tried the ResizeProcessor, BilinearInterpolation and BicubicInterpolation resizers all with the same result.

Here is my method with my latest attempt. Depending on how much memory I give the JVM it sometimes fails on the resize, other times is fails on the toRGB():

Sometimes a solution is so obvious it is embarrassing.

My real goal, now that I think about it, is to find the scale factor between the two images. Instead of scaling up image2, I can scale down image1. This is much less memory intensive. Then with regards to image2 I can just invert this scale factor.

OpenImaj - identify a shape

Asked 2018-Oct-22 at 09:24

My purpose is to identify a shape after having trained a classifer, similar to what's done in chapter 12 of The OpenIMAJ Tutorial http://openimaj.org/tutorial/classification101.html . Chapter 12 uses Caltech101 class which is not helpful to me because I want to use my own set of images to train a classifier. I created this working code which is based on Chapter 12:

If you just want to classify things with the model you've trained then ignore all the ClassificationEvaluator stuff - its just for computing accuracy, etc.

Take a look at http://openimaj.org/apidocs/org/openimaj/ml/annotation/linear/LiblinearAnnotator.html (the type of your trainer object). As your trainer instance is typed on FImage and String its annotate() and classify() methods will both accept an FImage that you provide as input and provide the classification result as output (in slightly different forms; you'll have to decide which fits your needs best).

QUESTION

How to set the initial centroids of KMColourSegmenter in OpenIMAJ library?

Asked 2017-Mar-17 at 08:40

I want to measure the time that KMColourSegmenter, in OpenIMAJ library, takes to perform the clustering.

If I didn't make the initial centroids fixed, rather than random, I can't make the measure the performance; because it will change every time, give different number of iterations , and vary in time to execute the clustering.

So how to make the initial centroids fixed i.e. setting them manually?

Update:

@Jon Thanks for the answer, I am trying to implement what you said. Could you check it, especially the "clusters" array I think this array doesn't make sense to initialize. Please, correct me if I am wrong.

Answered 2017-Mar-17 at 08:40

You'll have to implement this yourself; create a subclass of KMColourSegmenter and create a constructor that takes in the centroids, as well as any parameters needed by your choice of constructor in the KMColourSegmenter super class. Then in your constructor, after the call to super, use the this.kmeans.setInit() method to set a initialisation to use you predefined centroids. You'll need to implement a custom FloatKMeansInit subclass that lets you set the centroids externally, but this should be trivial as it only requires implementing a single method.

Update in response to amended question:

You shouldn't call initKMeans directly; that happens behind the scenes when you run the algorithm. You also need to populate the centroids array with the centroids initial centroids you want rather than from the bds. For example (untested):

QUESTION

OpenIMAJ library cannot read tiff files?

Asked 2017-Mar-06 at 11:55

I am using OpenIMAJ library, it is working well on "JPEG" and "PNG" files but on tiff files it is giving me an error. Here is the code:

ANSWER

Answered 2017-Mar-06 at 11:55

TIFF is a horrible format as it has many custom extensions which are not always supported by libraries. OpenIMAJ tries to get around some of these issues by using a batch of different libraries in order to read all sorts of different images, however in this case it's failing. As you've noticed there is a 10mb buffer limit which is causing an issue - increasing it to 100mb allows the image you linked to be loaded. I'll update the code to address this (as it's only a limit, it would seem that the underlying buffer is much smaller so this shouldn't cause any problems).

As a quick work-around until the new snapshot is deployed, you can load the image you linked with this:
