java – Scale back processing time of picture to form

I am making a easy recreation engine utilizing Java and have discovered a serious challenge.
To create correct collision detection I made a decision to transform a clear picture right into a java.awt.geom.Space object. Nevertheless the strategy I am doing this is perhaps fallacious or unoptimized.

To check it out, I attempted loading an virtually 200×200 (precisely 195×196) pixels picture. I ran this system 5 instances and that is the time it took

• 2900ms = 2s
• 2848ms = 2s
• 2999ms = 2s
• 2887ms = 2s
• 2871ms = 2s

Common time: 2,901ms
This is not superb particularly contemplating the dimensions of the picture.

Right here is the code I’m utilizing:

public Entity(BufferedImage picture) {
    this.picture = picture;

    entityArea = new Space();
    heightmap = new int[image.getWidth()];
        
    boolean heightFound = false;

    for (int x = 0; x < picture.getWidth(); x++) {

        for (int y = 0; y < picture.getHeight(); y++) {
                
            if((picture.getRGB(x, y) & 0xFF000000) != 0) {
                entityArea.add(new Space(new Rectangle(x, y, 1, 1)));

                if(!heightFound) {
                    heightmap[x] = y;
                    heightFound = true;
                }
            }

        }

    }
}

heightmap is used to refer the highest pixels for an entity
