Texture data decompression method based on image distribution

The invention discloses a texture data decompression method based on image distribution. The method comprises the following steps: judging which compression type a texel block belongs to according to the head of compressed data; corresponding endpoints and weights are retrieved; and interpolating the value of the texel according to the endpoints and the weights. The compressed data is fixed in length and code rate; and the decompression speed is high. 本发明公开了一种基于图像分布的纹理数据解压方法，根据压缩数据的头部判断该纹素块属于哪种压缩类型；取回对应端点和权重；根据端点和权重插值出该纹素的值。本发明压缩数据长度固定，码率固定；解压速度快。
