A method of Intra prediction coding for multi-view video coding, or three-dimensional video coding, the method comprising: receiving input data related to a current block, wherein the input data corresponds to depth data or texture data; determining a first filtering-disable-flag associated with a high-level video data to indicate whether to disable at least one filter from a filter group, wherein the high-level video data corresponds to a level higher than a current block level, wherein each filter of the filter group relates to boundary filtering, neighboring sample filtering, interpolation filtering or a combination thereof, wherein said at least one filter from the filter group comprises Intra Boundary Filter applied to boundary pixels of the current block using current reconstructed samples and neighboring reconstructed samples of the current block, or Neighboring Sample Filter applied to the neighboring reconstructed samples of the current block, and wherein said determining the first filtering-disable-flag comprises asserting the first filtering-disable-flag if the input data corresponds to the depth data for multi-view video coding or three-dimensional video coding, asserting the first filtering-disable-flag if the input data corresponds to the texture data in a dependent view in multi-view video coding or three-dimensional video coding, and dis-asserting the first filtering-disable-flag if the input data corresponds to the texture data in an independent view or a base view; if the first filtering-disable-flag is asserted: determining one or more selected Intra prediction modes from an Intra prediction mode group, wherein said one or more selected Intra prediction modes from the Intra prediction mode group correspond to DC prediction mode, Horizontal prediction mode, or Vertical prediction mode; and skipping said at least one filter from the filter group for the current block if a current Intra prediction mode of the current block belongs to said one or more selected Intra prediction modes. receiving input data related to a current block, wherein the input data corresponds to depth data or texture data; determining a first filtering-disable-flag associated with a high-level video data to indicate whether to disable at least one filter from a filter group, wherein the high-level video data corresponds to a level higher than a current block level, wherein each filter of the filter group relates to boundary filtering, neighboring sample filtering, interpolation filtering or a combination thereof, wherein said at least one filter from the filter group comprises Intra Boundary Filter applied to boundary pixels of the current block using current reconstructed samples and neighboring reconstructed samples of the current block, or Neighboring Sample Filter applied to the neighboring reconstructed samples of the current block, and wherein said determining the first filtering-disable-flag comprises asserting the first filtering-disable-flag if the input data corresponds to the depth data for multi-view video coding or three-dimensional video coding, asserting the first filtering-disable-flag if the input data corresponds to the texture data in a dependent view in multi-view video coding or three-dimensional video coding, and dis-asserting the first filtering-disable-flag if the input data corresponds to the texture data in an independent view or a base view; if the first filtering-disable-flag is asserted: determining one or more selected Intra prediction modes from an Intra prediction mode group, wherein said one or more selected Intra prediction modes from the Intra prediction mode group correspond to DC prediction mode, Horizontal prediction mode, or Vertical prediction mode; and skipping said at least one filter from the filter group for the current block if a current Intra prediction mode of the current block belongs to said one or more selected Intra prediction modes. determining one or more selected Intra prediction modes from an Intra prediction mode group, wherein said one or more selected Intra prediction modes from the Intra prediction mode group correspond to DC prediction mode, Horizontal prediction mode, or Vertical prediction mode; and skipping said at least one filter from the filter group for the current block if a current Intra prediction mode of the current block belongs to said one or more selected Intra prediction modes.
