Defective Pixel Replacement
The Pixel Replacement algorithm is based on a predefined bad pixel map (as an XML file), either
factory supplied (file loaded as “Factory Map”) or generated by the user (file uploaded as “User
Map 1”). The number of bad pixel entries is maximum 12. The following XML code sample forms
the template for the user to build bad pixel maps.
Note: Identifying bad pixels is the user’s discretion. Teledyne DALSA technical support can provide
guidance.
Methods
There are two replacement algorithms available to the user.
• Method 1: This algorithm replaces a defective pixel with the average value of the pixel to the
left and right of the pixel to be replaced.
• Method 3: This algorithm replaces a defective pixel with a neighbor.
