写一个matble关于红细胞数目检测界面设计与实现 涉及过程图：图像二值化、开运算和闭运算要求.GUI界面实现（含单选、下拉列表、滑动条或参数输入、输出，为好评设计）2.每一类问题至少两种以上处理算法支撑。源代码

以下是一个MATLAB程序的源代码，用于实现红细胞数目检测的GUI界面设计和实现。程序涉及图像二值化、开运算、闭运算等处理算法，同时实现了单选按钮、下拉列表、滑动条和输出框等GUI组件，方便用户进行操作和查看结果。

function varargout = red_blood_cell_detection_GUI(varargin)
% RED_BLOOD_CELL_DETECTION_GUI MATLAB code for red_blood_cell_detection_GUI.fig
%      RED_BLOOD_CELL_DETECTION_GUI, by itself, creates a new RED_BLOOD_CELL_DETECTION_GUI or raises the existing
%      singleton*.
%
%      H = RED_BLOOD_CELL_DETECTION_GUI returns the handle to a new RED_BLOOD_CELL_DETECTION_GUI or the handle to
%      the existing singleton*.
%
%      RED_BLOOD_CELL_DETECTION_GUI('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in RED_BLOOD_CELL_DETECTION_GUI.M with the given input arguments.
%
%      RED_BLOOD_CELL_DETECTION_GUI('Property','Value',...) creates a new RED_BLOOD_CELL_DETECTION_GUI or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before red_blood_cell_detection_GUI_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to red_blood_cell_detection_GUI_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
