The Image search by content is an area that is based on a set of low-level features such as histograms, textures, the distribution of colors, shapes an brightness. The structure element is a shortcut of the image may vary depending on the designer of the XML document and which may change according to application needs. The visual ap- pearance of the image is a permanent factor that undergoes no change. Therefore, we present in this paper a new method of search by con- tent based on Harris detector, Haar wavelet and Color histogram for the step of feature extraction to extract a binary signature for all multime- dia documents.Finally We estimate the similarities between codes and search relevant images with Hamming distance.
