The transformation from changed pixels to changed objects makes the proposed framework distinct with both the pixel-based and the object-based change detection methods.
Therefore, pixels represent a change when the inter-annual temporal dynamics is changed.
The results of these developments enabled us to adjust the lenslet array with a submicrometer precision and to mark the pixels of the sensor where the views do not register properly.

This allows to exchange detailed shading between pixels close to a surfel and approximate shading between pixels distant to a surfel.
The experimental results demonstrate that this novel approaches can decompose mixed pixels more accurately regardless of how much the endmember overlaps.

The proposed transform can change the position of the pixels and also can modify the pixels value, where Arnold transform can only reordered the pixels.
Principal component analysis helps us to understand the definitionof a statistical distance associated with each pixels, and using this dis-tance it is possible to identify those pixels labeled as bad pixels.
We also propose a robust method to threshold foregrounds to obtain a change detection mask of the moving pixels.
In the change detection application, the method offers much better separation between the changed and unchanged coherence pixels than existing filters.
We prove that MVES is indeed robust against lack of pure pixels, as long as the pixels do not get too heavily mixed and too asymmetrically spread.
Thus display panels that do not have enough pixel numbers can be used to display the entire elemental images with a large number of pixels.
It was found that determining an optimum threshold level between change and no change pixels of the difference DEM is important.
The findings confirm the advantage of the smallest pixels in this range and the advantage of square pixels over rectangular pixels.
This will cause the values in the image pixels to be different.
Furthermore, the proposed method reduces the probability of detecting noise-free pixels as noisy pixels and vice versa.
1000 2 pixels) can be processed in parallel.
