Program description (English)Open-source Java libraries, supporting generalized smart arrays and matrices with elements of any types (1 bit, 8/16/32/64-bit integers, 32/64-bit floating point values and any other Java types). The libraries contain a wide set of 2D-, 3D- and multidimensional image processing algorithms: linear filtering, mathematical morphology, rank operations, spectral transformation (FFT), and other algorithms, working over arrays and matrices. There is also skeletonization and measuring of binary images. The libraries use 63-bit addressing of array elements (all indexes and length are represented by 64-bit long type). So, it's theoretically possible to create and process arrays and matrices containing up to 2^63-1 (~10^19) elements of any primitive or non-primitive types, if OS and hardware can provide necessary amount of memory or disk space. Memory model concept allows storing AlgART arrays in different schemes, from simple Java arrays to mapped disk files; all necessary data transfers are performed automatically while every access to an element or a block of elements. Most of algorithms are based on wide usage of lazy evaluations. Typical operations, like elementwise summing or geometrical matrix transformations, are implemented via lazy views of the source array or matrix. For example, you can take a multidimensional matrix, rotate it (or perform any other affine or projective transform), and then extract a submatrix from the result. All these operations will be performed virtually (not requiring time), and actual calculations will be performed only at the moment of accessing elements, usually while copying the resulting matrix to a newly created one. Moreover, in many cases the libraries will 'understand' itself, that the user wants to perform rotation or another transform, and will split the matrix into suitable rectangular blocks (fitting in RAM) and choose the best algorithm for this task at the moment of copying operation.
Program description (Russian)Открытые (open-source) Java-библиотеки, поддерживающие обобщенные 'умные' массивы и матрицы с элементами любых типов (1 бит, 8/16/32/64-битовые целые, 32/64-битовые вещественные значения и любые другие типы Java). Библиотеки содержат широкий набор алгоритмов обработки 2D-, 3D- и многомерных изображений: линейные фильтры, математическая морфология, ранговые операции, спектральные преобразования (FFT) и другие алгоритмы, работающие с массивами и матрицами.Также реализована скелетизация и измерения бинарных изображений. Библиотеки используют 63-битовую адресацию элементов массивов (все индексы и длины представлены 64-битовым типом long). Таким образом, теоретически возможно создавать и обрабатывать массивы и матрицы, содержащие до 2^63-1 (~10^19) элементов любых примитивных или не-примитивных типов, если ОС и компьютер могут обеспечить необходимое количество памяти или дискового пространства. Концепция модели памяти позволяет хранить AlgART-массивы различными способами, от простых Java-массивов до отображаемых дисковых файлов; все необходимые передачи данных производятся автоматически при каждом доступе к элементу или блоку элементов. Большинство алгоритмов основаны на широком использовании 'ленивых' вычисление с автоматической оптимизацией для многоядерных процессоров.
