Law of cosines with vectors
Web11 apr. 2024 · Compressing the image causes less memory to be used to store the images. Compressing images increases the transmission speed of compressed images in the network. Vector quantization (VQ) is one of the image compression methods. The challenge of the vector quantization method for compression is the non-optimization of the … WebCosine law is basically used to find unknown side of a triangle, when the length of the other two sides are given and the angle between the two known sides. So by using the below formula, we can find the length of the third side: a 2 = b 2 + c 2 -2bc cos α
