New features and changes introduced in this version are

Block Enhancements

2–D FIR Filter

The 2-D FIR Filter block now supports separable filters.

Blob Analysis

The Blob Analysis block lets you specify the size of the blobs you want to find and to exclude the blobs touching the image border.

Color Space Conversion

The Color Space Conversion block supports conversions between the R'G'B' and HSV, sR'G'B' and XYZ, and sR'G'B' and La*b* color spaces.

Draw Shapes

The Draw Shapes block lets you draw filled polygons on your video.

Edge Detection

The Edge Detection block supports the Canny edge detection method for floating-point arithmetic.

Location Port of the Insert Text and Compositing Blocks No Longer Supports as Many Data Types

The Location port of the Insert Text and Compositing blocks used to support double-precision floating-point, single-precision floating-point, and Boolean data types as well as 8-, 16-, and 32-bit signed and unsigned integers. Now this port supports only double-precision floating-point and single-precision floating-point data types when the block input is a floating-point data type.

Compatibility Considerations.   You might need to change the data type of the signal input to the Location port.

MPlay

The mplay GUI can stop and start a Simulink simulation. Also, its interface has been enhanced, so it is easier to use and has greater capabilities.

Read AVI File, Read Binary File, and From Multimedia File

The Read AVI File, Read Binary File, and From Multimedia File blocks can return an end-of-file indicator, which lets you determine when the end of your video file has been reached.

Read Binary File and Write Binary File

The Read Binary File and Write Binary File blocks let you specify the byte ordering in custom files. You can choose between big endian and little endian data organization.

Fixed-Point Support

The Autothreshold block now supports fixed-point data types.
