* sam : image + prompt encoder, store embeddings * sam : add the dense img pe in SAM state (#401) * Add SAM decoder & output masks as png (#418) * Add loading of decoder layers in Model * Multiply by hypernet_layer_cnt for ctx_size on model load * Add decoder layers to py conversion script * Fix wrong and reversed tensor sizes for decoder * Add decoder transformer implementation * Add decoder hypernet and iou prediction mlps * Add transpose convolution operation and unit test * Finish mask decoder and write the decoder output in the model state * Output masks to png after removing padding and upsampling to original size - Also filter based on the iou treshold - Additionally filtering based on the stability score and crop boxes should be done * Add stb image write in order to output masks from SAM * Add transpose convolution 2d name and symbol to ggml ops static arrays * Comment out debug print in transpose convolution test to fix compilation ggml-ci * Multithread GGML_OP_ADD_REL_POS operation * ggml : fix GGML_OP_NAME array * Disable and comment out debug prints in SAM example * Add README for the SAM example * Calculate & filter based on stability score and calculate bounding box ggml-ci --------- Co-authored-by: Yavor Ivanov <[email protected]>
