jsharer验证码识别的c#实现

核心算法：简单字典匹配

先切割字符，二值化，将每个字符转换为01字符串之后进行字典匹配比较

 

        private string Translate(string charToTranslate)
        {
            var array = charToTranslate.ToCharArray();
            char max=' ';
            int maxScore=0;
            var results = digits.Select(digit =>
                {
                    int i = 0;
                    int s = 0;
                    var digitArray = digit.ToCharArray();
                    array.All(pixel =>
                        {
                            if (i < digitArray.Length-2)
                            {
                                if (pixel == digitArray[i+2])
                                {
                                    s++;
                                }
                            }
                            i++;
                            return true;
                        }
                    );

                    return new { name = digitArray[0], score = s };
                }
            ).ToList().All(pair =>
            {
                if (pair.score > maxScore)
                {
                    maxScore = pair.score;
                    max = pair.name;
                }
                return true;
            });


            return max.ToString();
        }
    }
