C-code generation support for more than 20 functions, including

regionprops, watershed, bweuler, bwlabel, bwperim, and

multithresh using MATLAB Coder

The following table lists the Image Processing Toolbox™ functions that have been

enabled for code generation in this release. For all target platforms, these functions

generate C code. If you choose the generic MATLAB Host Computer option in the

MATLAB

Coder™ configuration settings, many of these functions also generate C code

that uses a precompiled, platform-specific shared library (.dll, .so, or .dylib). Using

a shared library preserves performance optimizations in these functions but limits the

target to only those platforms that support MATLAB (see system requirements). For

a complete list of Image Processing Toolbox that support code generation, see “List of

Supported Functions with Usage Notes”.

If you choose the generic MATLAB Host Computer option in the MATLAB Coder

configuration settings, these functions generate C code that uses a precompiled,

platform-specific shared library.

This release also includes functions, listed in the following table, that previously

generated C code that uses a platform-specific shared library but now also generate C

code that does not require a shared library. You choose which by specifying the platform

in MATLAB Coder. If you choose the generic MATLAB Host Computer option in the

MATLAB Coder configuration settings, these functions generate C code that uses a

precompiled, platform-specific shared library.

App for batch processing sets of images

The toolbox includes new app that facilitates batch processing called the Batch

Processing App, shown below. The Batch Processing app enables you to perform an image

processing operation on a selection of files or the entire contents of a folder. Using the
