AB  - This work proposes a high-throughput implementation of the Otsu automatic image 
      thresholding algorithm on Field Programmable Gate Array (FPGA), aiming to process 
      high-resolution images in real-time. The Otsu method is a widely used global 
      thresholding algorithm to define an optimal threshold between two classes. 
      However, this technique has a high computational cost, making it difficult to use 
      in real-time applications. Thus, this paper proposes a hardware design exploiting 
      parallelization to optimize the system's processing time. The implementation 
      details and an analysis of the synthesis results concerning the hardware area 
      occupation, throughput, and dynamic power consumption, are presented. Results 
      have shown that the proposed hardware achieved a high speedup compared to similar 
      works in the literature.
