LAS Image Analysis

Automatic Analysis of Multiple Image Features

Meaningful Results

LAS Image Analysis is a sophisticated software module that
automatically performs feature detection, measurement and the
evaluation of multiple image features. In conjunction with the
Leica digital camera and microscope control, LAS can be used in
a diverse range of imaging fields. With it’s Sequence Panel, LAS
Image Analysis guides you through the set up process to simplify
the procedure of acquiring meaningful data and once established,
these settings can be used repetitively for future analyses.

LAS provides you with all you need to acquire a high quality
image of a specimen. Images can be acquired individually or
by automatically scanning a specimen using the optional LAS
MultiStep module. Images can then be processed by LAS Image
Analysis to enhance the edges of features so that they are
accurately measured. By simply using the thresholding functions,
you can specify the minimum and maximum gray scale values or
the hue saturation and intensity levels of a colour image to identify
the required image detail, prior to measurement.

If some minor debris is still visible after thresholding, then binary
processing may be employed to improve the image. A selection of
binary processing operations are provided and these can be tested
interactively to ensure that the image is optimised appropriately.
Once you have selected a method that is suitable, the conditions
can be stored for use with further images. LAS Image Analysis
also provides manual ‘image editing’ for the occasions when a
more hands on approach is preferable. This allows you to indicate
regions suitable for analysis or to identify the features to be
measured and remain in complete control of the specimen.
