Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 1 As shown, it is a flow chart of the muscle image processing method using Hough transform in the present invention. The present invention provides a muscle image processing method using Hough transform with simple operation, high precision and fast speed based on the muscle image collected by B-ultrasound , including the following steps:

[0022] (1) Muscle image preprocessing: use the grayscale transformation function to preprocess the image (such as figure 2 shown) to perform grayscale transformation and adjust the contrast of the image;

[0023] (2) Use the maximum inter-class variance method to carry out binary segmentation on the image according to the grayscale characteristics of the image, and segment the collected image into two sarcolemmas;

[0024] (3) Use Hough transform to find at least two peak ...

Abstract

The invention provides a processing method of a muscle image by utilizing Hough transform, which is to automatically mark positions of upper myolemma and lower myolemma by adopting Hough transform, and calculate the thickness between upper myolemma and lower myolemma by design algorithm. The method comprises the following steps: according to the characteristics of a muscle image, at least finding out front two peak points in a Hough matrix so as to detect positions of upper myolemma and lower myolemma in the image; extracting straight lines in positions of the upper myolemma and lower myolemma; according to information of the marked straight lines, calculating the sum of distances of corresponding points in the same row of upper and lower straight lines to acquire the area of muscle; and calculating the average thickness of muscle by dividing the muscle area by the muscle length, wherein the muscle length is the width of the image. According to the image processing method, the thickness of muscle can be quickly and accurately measured, and can be integrated into ultrasonic acquisition equipment for real-time measurement of muscle thickness.

Description

technical field [0001] The invention relates to an image processing method, in particular to a B-ultrasonic acquisition-based muscle image processing method using Hough transform. Background technique [0002] Muscle is an important tissue that constitutes the human body. It is distributed around various tissues, organs and bones. Its function is to generate contraction and guide movement, and it plays a vital role in sports. The composition of muscles is very complicated. Quantitative analysis and Assessing the state of muscle function is a difficult and hot topic in sports medicine and sports rehabilitation research. [0003] Ultrasound imaging is a real-time, non-invasive and portable imaging method, which has been widely used in various scientific research fields since it came out. Ultrasound is the first imaging technology that can assist in the diagnosis of muscle diseases. With the maturity of ultrasound technology, a large number of researchers use two-dimensional u...
