| | |
| My task is the one about [http://wiki.octave.org/SoC_Project_Ideas#Improvements_to_N-dimensional_image_processing N-dimensional image processing].
| |
| | |
| The project will consist of two parts.
| |
| The first part spans the first two thirds of the coding period and consists of extending the existing geometric transformation functions to handle N-dimensional images.
| |
| The second part begins work on geometric transformation objects.
| |
| It's difficult to predict how far it is possible to go in the allotted time, but the working target is to have a rough functional prototype of the affine2d object and an imwarp function that works with it.
| |
| | |
| I will also bring the relevant documentation up to speed, with examples where they are missing.
| |
| | |
| The first part of the project has its deliverables spread over two targets in order to provide some concrete results for the midterm:
| |
| | |
| ====Delivery target I (June 23)====
| |
| '''makeresampler, tformarray''' -
| |
| general transformation utilities; tformarray in particular handles transformations of a more general sort than just 2D. These functions are entirely new.
| |
| | |
| '''imcrop, imresize, imrotate, imtranslate, imtransform''' --
| |
| simple operations on images. These will be extended to support ND images, for which the relevant operation is applied planewise. Their 2D versions already exist in the image package.
| |
| | |
| The functions shall be in releasable form, with code and tests in their final forms. The documentation shall be in a reasonable state, but doesn't have to be finalized.
| |
| | |
| ====Delivery target II (July 10)====
| |
| '''impyramid''' - a compression algorithm; the paper is available [http://web.mit.edu/persci/people/adelson/pub_pdfs/pyramid83.pdf here]. This does not currently exist in Octave, but will be implemented in a form that is ND-compatible.
| |
| | |
| This function shall be delivered in finalized form. In addition, documentation for the functions from target I shall be finalized.
| |
| | |
| ====Delivery target III (August 18)====
| |
| Geometric transformation objects have the same function as the tform structs created by maketform, but are class-based.
| |
| | |
| A functional prototype of the '''affine2d''' object shall be delivered, along with an '''imwarp''' that works with it. The implementation should describe a paradigm that can be easily applied to further transformation objects.

| |
| | |
| In the event that the geometric transformation functions take less time than anticipated, they will be finished ahead of time and work on the transformation objects will begin immediately.
