Background:

Image reconstruction is a complex optimization challenge with practical applications.
Traditional gradient-based methods are unsuitable due to the non-explicit nature of the optimization objective.
Metaheuristic algorithms are effective for complex optimization problems with limited data or computation.

Purpose of the Study:

To introduce a novel metaheuristic search algorithm, progressive learning hill climbing (ProHC), for image reconstruction.
To address the limitations of gradient-based approaches in image reconstruction tasks.

Main Methods:

Developed the progressive learning hill climbing (ProHC) algorithm for image reconstruction.
ProHC incrementally adds transparent polygons to an image canvas, starting with one and adding more until a limit is reached.
Incorporated an energy-map-based initialization operator to enhance new solution generation.

Main Results:

ProHC successfully generated visually pleasing reconstructions for a benchmark set of four image types.
The proposed ProHC algorithm demonstrated significantly reduced computation time compared to existing approaches.
Experimental results validated the effectiveness of ProHC in image reconstruction.

Conclusions:

The progressive learning hill climbing (ProHC) algorithm is a viable and efficient method for image reconstruction.
ProHC offers a promising alternative to traditional methods, providing faster and visually superior results.
The developed algorithm advances the field of metaheuristic applications in image processing.
