Seek Software
Released: 2015-06-30
Report that update adds a large number of dead pixels http://www.eevblog.com/forum/testgear/yet-another-cheap-thermal-imager-incoming/msg628171/#msg628171
Camera Software: 1.3.0.0
Released: 2015-01-09 Camera Hardware: 0.0.0.5 Camera Software: 1.3.0.0 Application Software: 1.4.7.4 Image processing software: 1.6.0.0
Fixes gradient issues Improves fine detail Removes emissivity setting Reads 4 degrees low (target 42deg C, read 38deg C), not an issue in 1.4.0
Released: 2014-11-27 Camera Hardware: 0.0.0.5 Camera Software: 1.3.0.0
Claimed to address thermal gradient problem. Does not change gradient issue. All temperature measurements incorrect by large margin (30 degrees reads as 84 degrees) Was withdrawn by Seek, users reverted to 1.4.0
Camera Hardware: 0.0.0.5 Camera Software: 1.3.0.0 Application Software: 1.4.0.2

Processing is all done in Kelvin
Temperature limits are hardcoded to 253.15F - 523.15F
Communications from Seek discuss a flat field calibration.
Communications from Seek discuss a temporal drift algorithm. This algorithm is disrupted if the operation of the shutter is interfered with.
The functions exported by the compiled libraries can be listed.
From this we can see some of the post-processing steps used by Seek.
From 1.4.0.2 we have: A Kalman filter Median filtering Bilateral filtering Histogram creation

Temperature values, Seek vs calibrated FLIR Decent above 20 degrees, error grows below this point http://www.eevblog.com/forum/testgear/yet-another-cheap-thermal-imager-incoming/msg586977/#msg586977
Reading of objects at -18.5 degrees C are poor http://www.eevblog.com/forum/testgear/yet-another-cheap-thermal-imager-incoming/msg584884/#msg584884
