- Abstract: It is no doubt that the most important contributing cause of global
efficiency of coal fired thermal systems is combustion efficiency. In this
study, the relationship between the flame image obtained by a CCD camera and
the excess air coefficient ({\lambda}) has been modelled. The model has been
obtained with a three-stage approach: 1) Data collection and synchronization:
Obtaining the flame images by means of a CCD camera mounted on a 10 cm diameter
observation port, {\lambda} data has been coordinately measured and recorded by
the flue gas analyzer. 2) Feature extraction: Gridding the flame image, it is
divided into small pieces. The uniformity of each piece to the optimal flame
image has been calculated by means of modelling with single and multivariable
Gaussian, calculating of color probabilities and Gauss mixture approach. 3)
Matching and testing: A multilayer artificial neural network (ANN) has been
used for the matching of feature-{\lambda}.

FlameFinder is designed to accurately detect flames, even when obscured by smoke, using thermal images from firefighter drones during wildfire monitoring.
Traditional RGB cameras struggle in such conditions, but thermal cameras can capture smoke-obscured flame features.
To address this issue, FlameFinder utilizes paired thermal-RGB images for training. By learning latent flame features from smoke-free samples, the model becomes less biased towards relative thermal gradients.

Diffusion model-based image restoration (IR) aims to use diffusion models to recover high-quality (HQ) images from degraded images, achieving promising performance.
Most existing methods need long serial sampling chains to restore HQ images step-by-step, resulting in expensive sampling time and high computation costs.
In this work, we aim to rethink the diffusion model-based IR models through a different perspective, i.e., a deep equilibrium (DEQ) fixed point system, called DeqIR.
