Nowadays, touch screen technology makes drawing a sketch easier. It also makes searching and surfing easier for disabled children. Retrieving images with a sketch is a highly desired feature for disabled children with autism. The image retrieval system was defined as a computer system for searching, browsing and accessing the image. It is not easy for autistic children to recognize suitable keyword because of their lack of processing ability and memorizing the information in their mind; otherwise they are good in drawing sketch. In this paper, attention is placed on developing an image retrieval search engine based on sketch to aid children with Autism Spectrum Disorders in retrieving relevant images without needing to insert text based input.
