An image contrast adjusting method, processing device and readable storage medium
By using a dynamic threshold model and zone-specific differential adjustment, combined with the working state of the dual-balloon microcatheter, the problems of contrast distortion and detail loss in endoscopic image processing were solved, enabling precise observation of blood vessels and thrombi and improving the success rate of thrombectomy.

AI Technical Summary
Existing endoscopic image processing methods cannot dynamically adapt to the actual scene during surgery, resulting in image contrast distortion, loss of detail, or excessive enhancement of background noise, making it difficult to meet the needs of precise thrombectomy.
By acquiring images and simultaneously obtaining the working status parameters of the dual-balloon microcatheter, the region is divided into blood vessel, thrombus, and background regions. A dynamic threshold model is established, and an adjustment scheme combining grayscale and color is adopted to adjust the contrast of each region in a targeted manner. Combined with parameters such as balloon inflation pressure and aspiration negative pressure, regional differential adjustment is achieved.
It improves the detail of image observation, enhances the clarity of thrombi and blood vessels, and increases the success rate of thrombectomy.
