| Abstract: |
The spatial and temporal non-uniformities in infrared focal plane array (IRFPA), which is called as fixed pattern noise, results a slowly varying pattern on the thermal image thereby, degrading the resolving capabilities of thermal imaging system considerably. An adaptive filter based technique is presented to correct fixed pattern noise. This method uses kalman filter and corrects both the additive and multiplicative types of fixed patter noise thus eliminating the need of halting the operation of thermal camera for calibration. A FPGA based approach is presented for implementing the proposed method. The result obtained and the performance parameter of the algorithm is presented. |
